Message from the Chair
Chair, Department of Internal Medicine
Donald W. Seldin Distinguished Chair in Internal Medicine
Ruth W. and Milton P. Levy, Sr. Chair in Molecular Nephrology
Welcome to the Department of Internal Medicine at UT Southwestern.
Founded on a tradition of scientific inquiry that has culminated in multiple Nobel Prizes, today's Department of Internal Medicine at UT Southwestern is driven by a culture of creativity, collaboration, integrity, and excellence. Our physicians, researchers, and educators are united by a common purpose: to improve lives. To achieve this, we conduct groundbreaking research, we deliver nationally heralded care throughout North Texas, and we host one of the largest Internal Medicine training programs in the country.
Excellence in each of these domains is not an endpoint, but our ongoing commitment. Progress in medicine is rarely the work of a single discipline or perspective. It emerges from thoughtful partnership, grounded in mutual respect and guided by a shared sense of integrity. When we bring these principles to our work, we are able to achieve more than any one of us could alone.
I invite you to learn more about our people and our programs. In doing so, you will see how this collective effort translates into meaningful advances in medicine and, ultimately, into transformative outcomes for the patients and communities we serve.
Mission
To fulfill our mission of building a healthier future for us all, we educate medical students, residents, and postdoctoral fellows to the highest professional standards, prepare clinicians to deliver patient-centered, high-value, cost-conscious care, and advance discovery by answering fundamental questions in the mechanisms, prevention, and treatment of disease across the basic sciences and healthcare delivery.
By the Numbers
As of 2026, the department had 1,122 faculty members: 839 with primary appointments, 118 more from other departments who held secondary appointments, and 165 with adjunct appointments. The primary and secondary faculty includes:

These exceptional faculty lead UT Southwestern Medical Center's Internal Medicine programs to produce graduates who balance the core responsibilities of medicine: selfless dedication, competence, and compassion. As with the rest of UT Southwestern, Internal Medicine is pursuing the future of medicine, today.
Spotlight on Internal Medicine Grand Rounds
The SWAG (Supporting Women in Achieving Greatness) Committee invites you to Internal Medicine Grand Rounds, featuring Dr. Judith Regensteiner, Professor of Internal Medicine in the Division of Cardiology and Director of the Ludeman Family Center for Women's Health Research at the University of Colorado Anschutz, on Friday, Sept. 18 at 8 a.m. in D1.502.
For more than 30 years, Dr. Regensteiner has led federally funded research on the cardiovascular effects of type 2 diabetes, particularly in women, who often experience greater cardiovascular complications than men. Her work explores why diabetes reduces exercise capacity and how to improve cardiovascular health through studies of exercise physiology, vascular function, muscle biology, and advanced imaging. She also leads the NIH Building Interdisciplinary Research Careers in Women’s Health (BIRCWH) program at the University of Colorado and has been a national leader in women’s health research, mentorship, and scientific career development.
