James Galligan, PhD

Assistant Professor, Pharmacology and Toxicology

James Galligan, PhD, assistant professor, Department of Pharmacology and Toxicology—studies the link between cellular metabolism, environmental genetics and disease etiology. Keenly interested in post-translational modifications, his research focuses on reactive metabolites deleterious cell health. Current work centers on histone modifications derived from cell metabolism in diabetes and cancer.

Recipient of several Society for Free Radical Biology and Medicine Young Investigator Awards, he’s also received the Harold C. Hein Award for Outstanding Performance in Graduate Studies and Research and Norman Weiner Graduate Student Award for Research Excellence. His numerous journal articles and presentations focus on histones, oxidative stress and cell metabolism.
