Dr. LaBarge received a B.S. in Genetics from University of California, Davis, and a Ph.D. in Molecular Pharmacology from Stanford University. 

He became passionate about the biology of breast cancer during his postdoctoral training at the Lawrence Berkeley National Laboratory, with his mentor Mina Bissell, Ph.D., where he was an American Cancer Society Fellow, and where he built novel high throughput cell-based systems for studying human mammary stem cell fate decisions in the contexts of combinatorial microenvironments. 

In 2009 he won a Transition to Independence Award from the National Institute on Aging and joined the LBNL faculty.  In 2015 he was awarded the Era of Hope Scholar Award from the Congressionally Directed Medical Research Program to support his team's efforts to translate their laboratory findings into prevention-focused breast cancer therapeutics, which is a major focus of his current research.
