Brian J. North, PhD

Associate Professor

Biomedical Sciences

Brian J. North is an Assistant Professor in the Biomedical Sciences Department. After receiving his B.A. from Gustavus Adolphus College, he completed his Ph.D. from the University of California San Francisco with Dr. Eric Verdin. He then went on to his postdoctoral fellowship at Harvard Medical School with Dr. David Sinclair, and subsequently was a Research Assistant Professor at Beth Israel Deaconess Medical Center where he worked closely with the lab of Dr. Wenyi Wei. His main research focus is to understand the molecular and cellular pathways involved in regulating the process of aging, and how changes in these pathways contribute to the development of age-related diseases, with a primary interest in tumorigenesis.

Learn more about Dr. North's research.

Cancer Research Focus

The North lab studies the interrelationship between aging and cancer. We are particularly interested in the the role of the ubiquitin-proteasome system in targeting tumor suppressors and oncogenes in an age-dependent manner. 

Cancer Research Area(s)
  • Colon Cancer
  • Skin Cancer
  • Age Related Cancer Mechanisms


Research Focus

Molecular basis for aging and its impact on age-related disease susceptibility; Understanding the roles of E3 ubiquitin ligases in tumorigenesis; Regulation and function of NAD+-dependent deacetylases
