Students as Scientists’ Co-pilots in the Onset of Technology Transfer: A Two-Way Learning Process

To generate knowledge and technology transfer, universities are exploring new collaborative models. These new models aim to include actors that can have a positive impact on the technology transfer efforts of engaged academics. While open and collaborative models for technology transfer are seen as promising alternatives to the patent-centric linear model, there are limited insights on how these collaboration processes unfold and on their possible implications for the commercialization of new technologies. We explore the dynamics between the focal actor, i.e., the scientist, and a new actor in technology transfer, i.e., the students, in a university setting. We use an inductive, embedded multiple-case study to explore the contribution of knowledge interactions between scientists and students on the first steps of the technology transfer process. Our results suggest that the students’ contribution in the initial stages of the technology transfer process is influenced by the level of the scientist-student team consensus on the technology function as well as the flexibility and openness of the scientist to reconsider the technology meaning. We contribute to the ongoing debate on alternative technology transfer models and on the possible roles of students in academic ecosystems.


Introduction
In response to the call for a greater contribution to economic growth and to address societal issues, universities strive to diffuse scientific knowledge and engage in technology transfer activities (Alexander et al. 2018). Although this has been part of innovation policy for decades now (Wright et al. 2007), public research universities still face a growing pressure to commercialize research results through licensing and/or new businesses (Knockaert et al. 2011). Considering the oftentimes disappointing results when measuring the number of high-growth university spin-offs (Mustar et al. 2008;Siegel and Wright 2015) and the low levels of income generated through licensing technology (Weckowska et al. 2018), it is not surprising that there is an intensive debate about the necessity to rethink technology transfer processes (Hayter, Rasmussen, et al. 2018).
Arguably, the patent-centric linear models of technology transfer are not the only path to generate societal and economic impact (Fini, Rasmussen, et al. 2018). Plus, the focus on patenting could limit the formal participation of the TTO in alternative paths or models for technology transfer (Bradley et al. 2013;Hayter, Rasmussen, et al. 2018). While the existing models work for successful scientists that can hold multiple hats and deal with conflicting sources of pressure and tension (Casati and Genet 2014;Mangematin et al. 2014). It might not work that well for young scientists or scientists in departments with limited technology transfer experience, lacking role models, or with scarce organizational support (Greven et al. 2019).
Building on the observation of how students get involved in academic spin-offs to bridge between the technology and the market (Boh et al. 2016;Hayter et al. 2017), we propose to expand prior student entrepreneurship research to study how the student could contribute in the early stage of a potential technology transfer process (before invention disclosure). More specifically, our research question is: how do students contribute, through an educational program, to the initiation of scientists' technology transfer processes?
We use a longitudinal embedded multiple-case study design to observe four projects where scientists and engineering students work together in the context of a master's educational program in a university. This provides an excellent context to explore the research question, with scientists working on cutting-edge technologies but with limited experience on technology transfer or academic entrepreneurship, and still searching for possible market applications.
Our results are synthesized in an explanatory framework, it describes the different stages and the connecting mechanisms in the scientist-student team collaboration to explore opportunities for technology transfer. We discuss how the consensus on the technology-market function and the flexibility (or rigidity) of the scientist's technology-market focus influence the contributions of students, allowing them to take a co-pilot role in the collaborative process. We contribute to the ongoing debate on collaborative models for technology transfer (Bradley et al. 2013), and on the identification of additional functions that students can develop in the university ecosystem (Hayter, Nelson, et al. 2018;Siegel and Wright 2015) and how being exposed to the overall technology transfer process can enrich their educational experience. This paper is structured as follows; in the theoretical background, we position our study within the context of new collaborative models for technology transfer, the role of the scientists, and prior research on student entrepreneurship. The next section presents our research design, method, setting, and data. Then we present the results of the iterative process of data analysis. Finally, we discuss our findings and implications, we conclude acknowledging the limitations and describing avenues for future research.

Theoretical Background
In the search for a broader and deeper societal impact, the technology and knowledge transfer activities become a pivotal element in the transition towards an entrepreneurial university model (Guerrero et al. 2015;Klofsten et al. 2019), where science commercialization connects scientific research with societal and economic impact (Fini, Rasmussen, et al. 2018). However, these ambitions rely on a productive collaboration between the scientists and the support infrastructure, i.e.
Technology Transfer Office (TTO), in the university (Nilsson et al. 2010;Walter et al. 2018). This relationship has been studied from the perspective of the scientist and the TTO. Prior research has studied, for instance, how scientists respond to the introduction of monetary rewards to patenting (Lam 2011), incentives to become academic entrepreneurs (Kochenkova et al. 2016), or the acknowledgment of industry-related activities in promotion assessments (Fini, Jourdan, et al. 2018;Walter et al. 2018). From the TTO perspective, researchers have, for instance, explored how their organizational setup and support would influence scientists' behavior (Meoli and Vismara 2016), or why TTO's visibility (or lack of) explains why scientists would bypass them (Huyghe et al. 2016).
At the core of this discussion is the call to assess how the TTO' organization and objectives contribute to the university's goals (Fitzgerald and Cunningham 2016), whether the TTO business model fits with the specific context and ambitions (Baglieri et al. 2018), and how the TTO's competencies complement the scientists' weaknesses in research commercialization (Rasmussen and Wright 2015).
In their review of TTOs models, Bradley et al. (2013) suggest that the literature describes a traditional model where the TTO is a gatekeeper of technology transfer activities, following a patent-centric linear sequence of activities. They suggest instead, to consider a collaborative model, where the frontend is open for (formal and informal) interactions involving scientists and other university actors, and where the back-end is organized as a response to the specific needs of the potential technologymarket application combinations (including the patent-centric approach).

Reducing Individual Barriers to Technology Transfer
Part of the ambition of the collaborative model is to downsize the initial burden to enter the technology transfer process. Scholars have accumulated evidence of the positive impact that informal interactions have to trigger engagement with the broader academic ecosystem beyond scientists' teaching and research responsibilities (Azagra-Caro et al. 2017;Hayter, Nelson, et al. 2018;Perkmann et al. 2013). As a result, the locus of attention is not that much on the internal (and formalized) procedures of the TTO, but on how to increase the supply of research commercialization ideas. In other words, on how to increase the level of activity in the pre-invention disclosure phase.
Prior research made visible that a substantial part of research with commercial potential never enters the technology transfer process (Bercovitz and Feldman 2008;Thursby et al. 2001). Reasoning that this is due to individual choices of the scientist (Thursby et al. 2001) motivated by (1) unwillingness to allocate time to applied R&D activities, (2) concerns about research publication delays, (3) negative perception of commercial activities, or (4) negative perceptions of the TTO's capabilities.
However, there are underlying factors such as the presence (or absence) of a personal network that connects the scientists with the industry's problems, or the scientists' self-efficacy perception in relation to activities related to academic entrepreneurship or technology transfer in general (Foo et al. 2016). Therefore, it is a rather path-dependent behavior (Thune and Gulbrandsen 2014), that is difficult to initiate (Bienkowska and Klofsten 2012). In addition, there are self-reinforcing mechanisms, for instance, the presence of peers or role models in the same department (Bercovitz and Feldman 2008;Foo et al. 2016), or a supportive (towards research commercialization) department head/chair contributing to create the organizational climate for such proactive behavior (Aldridge et al. 2014;Greven et al. 2019;Hottenrott and Lawson 2017).
Thus, reviewing the evidence it is arguable that to reduce barriers it is necessary to facilitate the initiation of the path. Considering the individual reinforcing mechanisms and the dependence on a supportive organizational climate, the missing element is a spark that could trigger an initial positive experience in technology transfer activities. Given that the challenge for some of the scientists is to have this first collaboration with an outside actor (Thune and Gulbrandsen 2014), an option could be to search for this spark inside the university context.

The Role of Students and Educational Programs in Technology Transfer
Inside the university context, students have received increasing research attention to further explain their contribution to the technology and knowledge transfer activities (Hayter et al. 2017), as it has been observed to be more significant than previously expected (Siegel and Wright 2015).
First, and foremost, researchers have observed that recent university graduates are more likely to start a business than university faculty, and with substantial and direct economic impact (Acs et al. 2016;Åstebro et al. 2012). But it is not only recent graduates that contribute to transfer internal knowledge to society, graduate students can also have a substantial contribution. Ph.D. students and post-docs can contribute to the establishment of academic spin-offs, helping to initiate the new venture creation process or even taking the role of co-founder (Hayter et al. 2017). The more exposed they are to industry partners during their PhD the more likely they also engage in entrepreneurial activities afterward (Bienkowska et al. 2016).
Second, students are also an indirect driver of knowledge and technology transfer. Students often take the role of a bridge between the academic and industry contexts, they can help to start informal and formal activities with firms (Löfsten et al. 2020), and effectively establish the first contact with the industry that could lead to a positive impact on research and valorization activities (Galán-Muros and Plewa 2016). Plus, students, in contrast with research-focused scientists, could see a reputational value on their engagements with the industry (Huszár et al. 2015), providing them with practical insights and potential future career opportunities.
Finally, most of the interactions between scientists and students occur in the context of students' educational programs. Thus, such programs could provide an ideal context to activate universityindustry collaborations that could lead to technology transfer initiatives (Kunttu 2017). But, while entrepreneurial education programs have become popular in disciplines like business and management, the a priori high potential STEM programs have only recently started to adopt such courses in their curriculum (Kleine et al. 2019;Piperopoulos and Dimov 2015;Snihur et al. 2018). In this direction, the introduction of technology commercialization education (Barr et al. 2009), technology entrepreneurship (Kleine 2020), or more generic entrepreneurship education programs for technical and engineering students (Secundo et al. 2016;Snihur et al. 2018) could be a promising avenue to generate the much-needed connection between scientists and students educational goals with a potential contribution for the universities' technology transfer (Bolzani et al. 2020).
While the contribution of students in the later stages of technology transfer, as student entrepreneurs (Åstebro et al. 2012), co-owners of spin-offs (Boh et al. 2016;Hayter et al. 2017), or surrogate entrepreneurs (Würmseher 2017), is increasingly visible. Less is known on how they could participate, as part of their educational programs, in triggering scientists' interest to search for market applications and to engage in the early stages of the technology transfer process. Therefore, we propose to explore the following research question: how do students contribute, through an educational program, to the initiation of scientists' technology transfer processes? With a particular interest in the knowledge and perspectives exchanges that could contribute to both, the student and the scientist's learning on technology transfer.

Method and Research Setting
Given the limited theorizing as well as empirical evidence on our specific research question, we employ an inductive longitudinal multi-case theory-building design (Eisenhardt and Graebner 2007).
This approach also fits with our process-focus to study the phenomenon and how it evolves across time (Gehman et al. 2017;Langley et al. 2013;Van de Ven and Poole 2005). We use an embedded design to explore the effects of the differences in individual scientist profiles and technology types in a homogeneous context, in line with similar studies (see Knockaert et al., (2011)) and multiple-case research design guidelines ( (Eisenhardt and Graebner 2007;Gehman et al. 2017). The design also aims to respond to the call for more in-depth, and rigorous, qualitative studies in technology transfer research (Cunningham et al. 2017).
Our setting is an engineering master's course (semester project) at a science and technology institute.
The institute is part of a multi-campus university and its research focus is on nanotechnology and mechatronics. The institute hosts several advanced research groups and educational programs. The course is designed to expose students to the technology entrepreneurship and innovation challenges and opportunities, it is formalized as follows: (1) an invitation was shared with the institutes' scientists to participate in the course, (2) the scientists prepared a short pitch (and a short written proposal) describing a promising technology or research they had been working on, (3) the students were informed of the possible projects and they self-organized in groups, (4) in an open voting process they selected a project (and scientific partner) after hearing the scientist's pitch.
This was the kick-off of a 5 months collaborative project. The course contents followed a similar approach to those used in the NSF I-Corps (Huang-Saad et al. 2016) and the market opportunity navigator (Gruber and Tal 2017). The final deliverable of the course is a short business case presentation of the technology-in-use. The course has mandatory intermediate deliverables (organized as milestone reports), guidelines on the importance of weekly updates (short meetings) between the scientist and the students, and checkpoints were the scientist and students can exchange viewpoints and adjust the project development.

Case Study Selection and Data Collection
We applied theoretical sampling of our cases in an embedded multi-case study approach (Eisenhardt and Graebner 2007;Gehman et al. 2017). We did so as we could select from the different responses that were received from the scientists in the institute, we invited to participate in the course those that a priori would contribute to clarifying the effects of the different sources of expected heterogeneity. This is differences in the technology maturity and the scientists' profile; while keeping the other potentially influencing factors as homogeneous as possible: research context (institute & university objectives and incentives), geographical setting (campus environment), and students' profiles (engineering).
Prior research has identified that both the technology value maturity and the characteristics of the scientists (status, reputation, experience…) can be influencing factors on how they approach the technology transfer process (Azagra-Caro and Llopis 2018; Perkmann et al. 2013), and the likelihood of successful commercialization (Kirchberger and Pohl 2016). We used academic status (position) to select among scientist characteristics, to differentiate across technologies we used the concept of the technology readiness level (TRL), as adopted by Mankins (2009). We acknowledge the critique that the perception of technology readiness is highly dependent on organizational specifics (Heslop et al. 2001), and that it is difficult to precisely determine the commercialization potential of early-stage technologies (Galbraith et al. 2010). Nonetheless, we use the TRL terminology as it allows for crosscase comparisons. The TRL describes the functional maturity of technology from basic discipline research (TRL 1) to system test, deployment, and operations (TRL 9). The maturity levels of the technologies brought by the scientists under study are in the mid-maturity levels: research to prove feasibility, and technology demonstration levels (TRL 3-6). In this study, the TRL level was determined by the scientist and validated by the researcher collecting the cases. The four different cases that were finally selected and studied are presented in Table 1. During the five months of the project, we collected data at three points (waves). At the beginning of the project, we collected the scientists' pitch document, their academic CV, and their initial technology application idea (if any). Halfway, we conducted semi-structured interviews with the student teams and individual interviews with the scientists. At the end of the project, we interviewed again the scientists and contrasted their insights (to increase data validity and reduce qualia) with the student team's reflection reports and interview data, following the standard procedures of data triangulation to increase accuracy (Hallen and Eisenhardt 2012).

The 16 semi-structured interviews (three with each scientist, one with each student teams) lasted between 16 and 39 minutes. In each interview, we covered the status of the project (including the market and technology situation), the ongoing challenges and opportunities, the learnings (positive and negative experiences), as well as the plans for the next steps. All interviews were transcribed.
Together with the idea pitches, the project group reports, and the individual reflections, this resulted in a total of approximately 54,000 words as data corpus, distributed across the four case studies.

Data Analysis
Applying theory-building data analysis techniques according to Eisenhardt (1989), we first completed a within-case analysis and then turned to a cross-case analysis to identify similar themes across the multiple cases (using NVivo 12). Our initial focus (following our research question) was on understanding the students' contribution to the scientist's technology transfer intentions and awareness, in the within-case analysis we identified that this contribution was evolving as the project advanced. This guided our first analysis round to establish whether we observed changes in the relationship between the students and the teams during the duration of the project. As we identified a similar pattern across the projects, we compared our findings with prior research, this helped us to characterize each of the different stages (specify the dimensions that characterize them).
At this point, we shifted our focus to the cross-case comparison, we went back to the case data to decipher what could be the mechanisms driving the change between the stages. Again, we iterated our emerging theoretical insights (propositions) with prior research, helping to refine and anchor them. Three researchers revised the quotes and coding and, in doing so, systematically developed the final themes and propositions through intense dialogue. Next to the triangulation of the data, this assured reliability of the data analysis. Once we had correspondence between the data, the theoretical insights (constructs and propositions), and prior research, we diagramed and finalized our explanatory framework (process model).

Results
We organize our results in two parts. First, we describe the process stages that emerged through the within-case analysis and that were then validated in the cross-case analysis. Second, we elucidate, in more detail, the mechanisms (as propositions) that capture how the interactions between technology, market, and scientist's drove this collaboration process back and forth.

A process-view on building the technology transfer opportunity
To discern across the different stages, we observed three dimensions that, based on prior literature, We used the extant work on this topic to help us further characterize each stage. Finally, we identified a correspondence between our data and prior research that described how social and cognitive proximity is seen as an enabler for university-industry collaboration (Steinmo and Rasmussen 2018;Villani et al. 2017), this last dimension helped to capture how the relationship between the students and the scientist was influencing (and being influenced) by their knowledge exchanges. Taken together, the three dimensions contribute to characterize each of the proposed stages (see Figure 1).

Figure 1. Stages in the process of building a technology transfer opportunity
The first stage, Giving meaning to the technology captures the initial challenge that the scientist encounters when working with the students. The scientist needs to find a meaning for the technology, reframing the value of prior research (his prior knowledge) or technology development into a potential market application. Prior research has identified that this is a key challenge in the search for applications beyond the scope of an individual's prior knowledge (Gruber et al. 2013). This generates an initial tension; the students express their need to know what the technology "means": "our questions to her were purely (mostly) with respect to the technology and how it will work" (fruit Sensor -student group). However, from the scientist's viewpoint this requires efforts to find explanations and meanings "for them (students) it is tricky to actually grasp, get the core, essence of what we are trying to do (in research)" (Clever Charge -scientist).
At this stage, a low TRL makes it cumbersome for students to relate to the technology and the possible applications. Further, advanced technologies, such as new plasmonics approaches to develop nanosensors (as used in the fruit sensor or pollution sensor), require an initial understanding of the chemical and physical theories behind the technology. The scientist takes the role of an expert researcher of the technology and tries to bring the student group up to speed, guiding them through the key principles that need to be understood to find possible meanings, making sense of the technology features and possible benefits. This helps the scientist to find a meaning for the technology • Technology complexity hinders student's ability to contribute.
• Tech readiness level limits market exploration.
• Scientist as expert, responds to requests.
• Tech development limits student´s ability to "represent" the technology.
• Initial market application is determined.
• Scientist as colleague, support and guidance.

Uncovering market application
Tech transfer opportunity assessment • Tech development as enabler for further engagement.
• Market opportunity is identified.
• Scientist as information receiver, potential partner.

Technology development status
Collaboration status Tech-Market combination status beyond the specifics of the research behind it. Additional quotes to illustrate this stage can be seen in Table 3.

S2: Uncovering market application
We improved the technology more and more, but the companies are not really interested in that. So, we thought first we have to identify who is the customer, what kind of things they want into that and then we will upgrade the product.

Midterm interview (student teams)
Our contribution has been mainly finding the potential customers. The second stage Uncovering the market application describes the identification of possible market applications for the technology. Prior research highlights that the establishment of a technologymarket combination has a significant impact on the formation of opportunity beliefs (Gregoire and Shepherd 2012), and thus could be a driver of further action (Mitchell et al. 2008). This means that the students' contribution is to "find the potential customers" (mini-vacuum -student group), this involves "identify who is the customer, what kind of things they want" (pollution sensor -student group). In words of one of the scientists, it is that "overview of the market…what they (the students) are trying to do" (Clever Charge -scientist). Interestingly, as the students overcome the challenge to present the technology to potential customers or interested parties, the scientist starts shifting roles, from being only a technology expert to becoming a team colleague offering support and guidance. It is in this stage when the students start to accumulate market knowledge and industry interactions that are seen as potential new inputs for the scientist.

Midterm interview (student teams)
Finally, the third stage: Technology transfer opportunity assessment, depicts how the agreement on a potential market opportunity generates a decision option for the scientist, to either engage further in the technology transfer process or abandon the specific technology idea. This stage resonated with observations in decision-making processes were individuals have to decide whether to take the plunge or pull the plug (Bakker and Shepherd 2017). This final stage gave the scientist the answer to "should we go for this project or not" (fruit sensor -scientist). The identification of a market opportunity is seen as a facilitator of further technology development (and value); "now we have a base for this (the product), now we can jump through some TRL levels much faster" (pollution sensor -scientist). It is at this stage where the researcher takes a different role, receiving and processing new information: "we get a good overview of the potential of this commercialization idea" (mini-vacuum -scientist).
Even though the focus is on the potential of the market application, the technology development status has an impact on the readiness of the opportunity and on the future expectations, for both, the scientist and the students, and consequentially on their future engagement in the technology transfer process.
The overall process has a dynamic nature; during our observation time, the projects evolved through (sometimes doing iterations backward) all stages. Thus, it is particularly valuable to better understand what drives the changes of stage. The mechanisms behind these changes are described as propositions (P1 to P4) in Figure 2. The illustrative quotes of the data that supported these propositions can be seen in Table 4.

From giving meaning to the technology to uncovering a market application
At the first stage of the process, the challenge is to uncover how the technology works and what possible functions it can have. Thus, a requirement for further action is to narrow the possible functions of the technology. One student group expressed this as the need to "build a kind of a prototype which we can take to the people to show this is the actual way this is going to work" (pollution sensor -students). This creates an apparent paradox, feedback is needed to guide the technology development, but to get feedback there needs to be an agreement on a plausible function to create the first prototype. As one of the scientists stated, there is a need for "a fully operational prototype…it is better when you have an idea … you are able to judge" (pollution sensor -scientist), but again this requires an initial consensus on a technology function. Therefore, we suggest that: something new" even if it "has to be from scratch" (fruit sensor -scientist). This triggers a change in the scientist's role in the collaboration, namely from being an expert to becoming a colleague (peer) in the students' team. For instance, one of the scientists was explicitly describing that "even if people are not interested in this (the scientist's initial technology application idea), it is helpful (to get negative feedback), because we can decide to follow another path (pollution sensor -scientist). As a result, we would argue that: Proposition 2: The more focused (fixed in her/his role and ideas) the scientist, the less likely he/she considers alternative market applications.

From a market application to a technology transfer opportunity
The connection between the second and third stage requires the consolidation of a possible market opportunity and a closer understanding of the current status of the technology and its plausible future evolution. Interestingly, almost any type of market response (even if somewhat negative) increases the interest of both students and scientists. As new insights can be seen as obstacles but also opportunities: "if we make it smaller and lighter…then there is a market…and we can sell it for less than competitors…that sounds good, so we started and then we realized, ok, it is not that easy" (minivacuum, students), or from the scientist viewpoint: "we can really think about to start some small company, probably in collaboration with the workshop, and to make a few prototypes" (mini-vacuum, scientist). The realization that the technology has a potential application often comes as a positive surprise to the scientist. The students help to uncover new information on the market structure and demands, often also proposing applications that were not considered a priori. Therefore, we propose that: Proposition 3: The greater the market response on the technology application, the more likely the scientist engages with the opportunity.
However, the exploratory nature of the process might clash against the pre-established ideas that the scientist has regarding the uses of the technology. This potential setback is different from the one observed between stages 1 and 2. It challenges the actual contribution of the technology for a specific market application. This generated for instance a tension in the Clever Charge team, where the scientist and students' team could not agree on whether the advantage of the technology was a part of an existing solution, or as a standalone product. In the case of other cases, this is not a problem: "whenever we talk to somebody from the industry and they say that they have a different need…then we can build a completely different sensor" (pollution sensor -scientist). There is a difference in whether the scientist sees the potential outcome as a single, unique project that maximizes the potential of the technology, or whether the scientist views this as one initial project that could be followed by others "our project is very open-ended, this is the technology (advanced sensor) and it is up to you how we are finalizing this" (fruit sensor -scientist). As a result, we would argue that:  Pollution sensor scientist, 2 nd round interviews P3: The greater the market response on the technology application, the more likely the scientist engages with the opportunity.
He said we need to make it smaller and lighter and you don't need a heating or cooling system, but then there is a market and we can sell it for way less than like competitors which are selling it for 70.000€ and we were like, that sounds good, that's sound good, so we started and then we realized ok, it's not that easy.

Midterm interview (student teams)
In our research phase we say, ok we develop something and now we are ready to go outside the lab, so any door will be open for us, it is ok.
Pollution sensor scientist, 1 st round interviews If we have a market, then we can really think about starting some small company, probably in collaboration with the workshop, and to make few prototypes, to make few products.
Mini-vacuum scientist, 1 st round interviews

Our project is very open-ended, this is the technology, and it is up to you on how we are finalizing this, it should work with many different gases and this is not a problem.
Fruit sensor scientist, 1 st round interviews Our technology, or how to say, we are developing many different components that could at the end be assembled together in one sensing system. So, depending on the market requirements, whenever we talk to somebody from the industry and they say that they have a different need, we can still use some of these elements, some of the components, and then we can build completely different sensor Pollution sensor scientist, 1 st round interviews We had a lot of discussions; we got a lot of feedback and input and there was also sort of a product development during the phase of this project.
[…] The product was actually refined because of the feedback and what the students did.

Pollution sensor scientist, 2 nd round interviews
This is not exactly the device we had at the beginning, but it could be an opportunity to develop something new, but it would have to be from scratch. […] Yes, that means we would have to research new kind of sensors which are very cheap […], but then we would have to find out how to do that.
Fruit sensor scientist, 2 nd round interviews The combination of the process model and the mechanisms, described as propositions, result in the explanatory framework presented in Figure 2.  Hayter et al. 2017). Taking the viewpoint of the scientist, we propose to take a step backward and explore the potential contributions of students in the pre-invention disclosure phase, when the scientist is still unsure of the technology application and lacks experience and support to start the technology transfer process. By studying four cases of P2. The more focused (fixed in her/his role) the scientist, the less likely he/she considers alternative market applications.

• Tech readiness level limits market exploration.
• Scientist as expert, responds to requests.

• Initial market application is determined.
• Scientist as colleague, support and guidance.

Students as co-pilots in the first steps towards scientists' technology transfer activities
In our findings, we observe that for projects with low TRLs the contribution of the students is stronger when the researcher has a rather flexible and open perspective regarding the possible applications of the technology. This requires from the scientist the ability to adjust and change paths, to consider alternatives, and to reevaluate choices. This is a rather individual cognitive process strongly influenced by the mental model of the actor (Gary and Wood 2011;Johnson-Laird 1980). In this setting, the scientists' mental models influence their ability to use new information available to change (or sustain) their behavior and expectations regarding the technology transfer process. This challenges the often dominant logics in the research context where specialization, persistence, and narrow focus pays off (Kotha et al. 2013). For the students to be co-pilots, the scientist needs to also offer some degree of flexibility on which direction to go.
In our cases, it became clear that projects with higher TRLs meant that the researcher had already invested significant efforts in the development of the technology and might have built a preconception on what is a suitable business application or market for his/her technology (already found a possible meaning (Norman and Verganti 2014)). Nevertheless, a higher TRL facilitates a quicker understanding of the technology and motivates the students to have a "boundary spanner" function (Mangematin et al. 2014). This results in further engagement of the scientist as long as there is a consensus on the technology function, as it has also been observed with technology evaluation panels (Galbraith et al. 2010), the shared consensus becomes a driver of further action among the process stakeholders.
Thus, we contribute by identify a possible setup to open up the onset of the technology transfer process, in line with the suggestions to consider collaborative models (Bradley et al. 2013) were additional stakeholders get involved or take different roles as part of an emerging academic ecosystem (Hayter, Nelson, et al. 2018). Suggesting an additional role for students and proposing a collaborative model to reduce entry barriers for scientists considering engaging in technology transfer activities.

A two-way learning process in the onset of the technology transfer process
Taking part in such a collaborative process for technology transfer is also likely to render positive impacts for the different stakeholders. The scientist, subject to their flexibility and openness, acquires new information and knowledge about a potential market application for the technology. The collaborative process offers an experience in a limited-risk context (safer than launching an academic spin-off) where a potential negative (or null) outcome of the collaboration does not damage the scientist's reputation or academic status (Lam 2011).
Our findings also contribute to better understand why some research ideas never make it to the invention disclosure stage (Thursby et al. 2001), suggesting the need for external input or intervention that changes the path, or provides the necessary support to advance to a stage where it is more reasonable to take the plunge (Bakker and Shepherd 2017) and enter the formal technology transfer process in the university.
The students' learning is an essential counterpart in our framework. The development of technology commercialization competences has been an area of growing interest in the educational programs in science and technology fields (Barr et al. 2009;Nelson and Monsen 2014). Our findings contribute to this ongoing conversation on how TTO's traditional activities can become part of the educational programs (Bolzani et al. 2020), and how the TTO can also benefit from opening up their function to university ecosystem actors (Giuri et al. 2019). The different stages we identified, and the interaction dynamics between the scientist and the students' team, support the encouraging evidence found in similar educational initiatives were using business modeling tools or market exploration tools contributed to building entrepreneurial mindset skills in engineering students (Gruber and Tal 2017;Snihur et al. 2018).
Finally, our findings also provide evidence of the potential theorizing benefits from introducing insights from entrepreneurship research in the study of the ideation or initial opportunity development of the technology transfer process. The parallelisms between the figure of the entrepreneur considering an opportunity, and a scientist considering a technology application opportunity, allowed to enrich our findings with insights from entrepreneurial decision-making on how technology-market combinations could be assessed as potential technology transfer opportunities (Bakker and Shepherd 2017;Gregoire and Shepherd 2012).

Practical Implications for Technology Transfer and Policy
While the notion that TTOs need to find the right business model depending on the context their operate (Baglieri et al. 2018) is difficult to dispute, it is more challenging to identify new pathways to improve the technology and knowledge transfer in universities. Based on our explanatory framework, we suggest that an option is to share part of the traditional activities of the TTO with other actors in the academic ecosystem. We believe that this can particularly productive in settings were the TTO has limited resources or struggles to attract contributions from the scientific staff.
However, it is important to clarify that the adoption of educational arrangements like the one we studied is not absent of additional tensions and risks for the TTO. For instance, as it happens with other collaborative models for technology transfer, opening up the front-end of the process also means taking into special consideration how this type of arrangement can generate intellectual property rights (IPR) disputes in the future. Also, it is essential to connect the more or less informal activities with what would be the onset of the already established technology transfer activities that fall under the responsibility of the TTO.
Policymakers interested in seeing an economic and societal impact from the research activities in universities could find in our findings an inspiration for a low-cost intervention in science and technology educational programs. Nevertheless, this would be a precipitated shortcut. First, while students would benefit from the experiential learning of being engaged in technology transfer projects with scientists, the project still has to be designed and managed to ensure the course learning outcomes. And second, the collaborative experience we studied provides a small spark to scientists that already have an initial consideration for technology transfer opportunities; it does not replace the much-needed support, in particular for younger scientists, to build connections beyond the university boundaries and to help them generate scientific and societal impact.

Conclusions
In response to the increasing interest to identify alternative (Hayter, Rasmussen, et al. 2018) or collaborative (Bradley et al. 2013) models for technology transfer, we studied the learning dynamics between students and scientists in the preliminary commercial exploration of promising research.
Using as context a five months semester project, part of a master's educational program in a university, we analyzed four technology exploration projects in an embedded multiple-case study.
Our data suggest distinct stages of evolution and driving mechanisms that explain what made the collaborative project go forward or backward.
We contribute by introducing technology-meaning consensus between the scientist and the students, as a spur the move potential technology transfer projects forward. Nevertheless, we also identify that the rigidity of the scientist's focus and perceptions can be an obstacle to the exploration and possible identification of technology-market combinations. Paradoxically, this implies that engaging in this collaborative process with a well-defined idea on the new technology application could be counterproductive for the scientists. But, too open and vague ideas regarding the possible functions or uses of the technology limits student's engagement in the project onboarding.
This implies that technology transfer office managers could consider the participation in educational activities that promote collaboration between students and scientists, in particular in the stages before the traditional formal steps of the technology transfer process (i.e. invention disclosure). Such collaborations could open the door to redefining actors' roles (in this case students) in the technology transfer process, while also providing valuable learning experiences for both the students and the scientists.
We acknowledge the boundaries and limitations of our study. First, although we conducted several interview rounds and complemented our interview data with additional sources, we did not measure or capture in detail how the perceptions or attitudes of the scientists would change as a response to project setbacks or positive updates. Further research could explore how the scientists' perceptions of technology transfer change across time, and how the individual or contextual aspects influence how they process, absorb, and respond to such unexpected events. In this vein, we identified that the scientist's mental model could be a source of explanation on the different behaviors we observed.
Further research could measure the fixation (or confidence) of the scientist in their judgment of the different market applications, then study to what extent the strength of their mental model impacts on the likelihood of identifying a technology transfer opportunity that could be exploited in the future.
Second, we focus on the preliminary steps of the technology transfer process, leaving the opportunity for further research to explore similar arrangements in later stages of the technology transfer process.
Such arrangements could equally generate learning opportunities for students, still, it would be crucial that they are considered in light of the students' education and learning goals.
Third, it would be interesting to explore experiments that would combine different types of technologies, researchers, and student profiles (for instance including business students). This could help to uncover the combinations that have additional effects or factors that went unnoticed in our research design. For example, further research could explore aspects related to cognitive diversity at the team level, exploring in the context of technology transfer opportunities some of the emerging findings from other research fields ).
Finally, it would be particularly interesting to study the long-term effects of participating in such types of collaborations. For instance, exploring the effect on scientists' perceptions and intentions to engage with the industry or other technology transfer projects that involve external actors. Similarly, following up on the students' career choices could also help to decipher the long-term impact of being engaged in such collaborative experiences with scientists.
