How to know if someone produces good research?

Ideally I'd have the skills to identify good research but I'm still in my undergrad so that's a skill I'm still developing. 

Is there a fast way of knowing someone produces good research in a certain field? Especially identifying a "rising star".

I tried looking at number of citations on Google scholar but I don't think it's very accurate since older researcher are likely to get more citations. And some PIs produces 40+ publication a year so they're likely to get more citations. 

I could ask my mentors but they're likely going to suggest people that they know personally and/or only in their subfield of subfield.

And using their schools seems very snobbish.

This is a question that is hard to answer, because everyone has different metrics for "good" research, and you never know what direction research will take you. 

That being said: there are usually conferences in which you will see topics that generate great interest to the community. It is often hard to go for an undergraduate but they are certainly worth your time to get a "feel" for the community. 

Also, you can look at agencies that fund early career awards, like NSF CAREER (or even better, PECASE) or the NIH DP2 awards. These awards are considered for "rising stars" at least by their funding agencies. 

More important that any particular qualification of good research, perhaps it be best to take a deep look at the fields YOU'RE most interested in. A passion is a passion and you can usually find good problems if you're inquisitive and creative enough.
