Tara Tassin, Ph.D., is an Instructor in the Department of Internal Medicine at UT Southwestern Medical Center, and a member of its Division of Cardiology.

Originally from Illinois, Dr. Tassin earned her bachelor’s degree in biochemistry from the University of Dallas and her doctorate in molecular biophysics at UT Southwestern. She completed her advanced training through postdoctoral fellowships in the pharmacology and psychiatry of addiction at UT Southwestern, and joined the faculty in 2019.

Dr. Tassin’s research focuses on molecular mechanisms underlying Duchenne muscular dystrophy-associated cardiomyopathy and heart failure. Her investigations have resulted in several publications in peer-reviewed journals.

In addition to her research at UT Southwestern, Dr. Tassin serves as a mentor to graduate and medical students, as well as college and high school students.

She is a member of the American Heart Association.
