Saying Yes to Science and Service  When Shane Killarney began medical school at Duke University, he spent a month conducting research in the lab of cancer biologist Kris Wood, PhD.

David Cortez, PhD, learned both large and small lessons during his time as a trainee in the Duke Department of Pharmacology and Cancer Biology (PCB). At the root of them all: the importance of asking questions and not being afraid to learn. He still draws on those lessons now in his current role as the Richard N. Armstrong PhD Chair for Innovation in Biochemistry at Vanderbilt University School of Medicine.
