Debbie Hsu is a quality assurance/quality control  laboratory supervisor who, 10 years ago, joined  Medarex, now part of Bristol-Myers Squibb. At the  company’s Redwood City, California, facility, this  “cold room” houses research antibodies to be  distributed to scientists across Bristol-Myers Squibb  to study new targets that may lead to groundbreak - ing therapies like  Yervoy  (ipilimumab) to fight  cancer. Researchers in Redwood City produce cell  lines used in developing new monoclonal antibod - ies, some of which may eventually become clinical  candidates in the company’s growing pipeline of  medicines that help the body’s own immune system  fight tumor cells.
