Nicholas Lam, Ph.D., is an Assistant Instructor in the Department of Internal Medicine at UT Southwestern Medical Center and a member of the Division of Cardiology.

Originally from Melbourne, Australia, Dr. Lam holds a bachelor's degree in reproductive and developmental biology from the University of Melbourne and a degree in stem cell biology from Monash University with honors, where he also earned a doctorate in cardiac regeneration.

He completed two postdoctoral fellowships at UT Southwestern, studying heart regeneration in the lab of Dr. Hesham Sadek and molecular biology in the lab of Dr. Eric Olson. He joined the UT Southwestern faculty in 2020.

Dr. Lam’s research interests include cardiac regeneration, cardiomyocyte proliferation, and the cell cycle. Dr. Lam is interested in finding strategies to coax rarely dividing cardiomyocytes to proliferate to help regenerate the heart after injury. In addition, he is developing protocols to measure cardiomyocyte proliferation. His investigations have resulted in several publications in peer-reviewed journals and contributions to two book chapters.

Dr. Lam serves on the editorial board of Frontiers in Physiology and is an ad hoc reviewer for Frontiers in Physiology and Scientific Reports.

Personal Note

Outside the lab, Dr. Lam enjoys experimenting with his cooking, food, coffee, traveling, and exercising.
