Program Leadership
UT Southwestern is a premier institution with a rich history of excellence and widely recognized accomplishments in medicine and the life sciences. As a proud graduate of its Internal Medicine residency, I can personally attest to the transformative nature of the residency and fellowship programs led by our Department. With three diverse clinical training sites, our residents gain exceptional clinical acumen while learning alongside world-class faculty—many of whom are pioneers in their fields.
The Department of Internal Medicine carries a longstanding tradition of innovation, offering residents abundant opportunities to engage in both clinical and research pursuits. Under the leadership of Dr. Salahuddin “Dino” Kazi, together with the Associate Program Directors and Chief Residents, our residency program embodies the pursuit of knowledge, discovery, and patient-centered care that define UT Southwestern.
Our program is enriched by the diversity of perspectives and experiences among our trainees and faculty, creating an environment that inspires everyone to reach higher—whether in patient care, education, or research. The close ties between our housestaff and our outstanding faculty are at the heart of our Department’s success. At UT Southwestern, we remain dedicated to training the next generation of leaders, preparing them to deliver the very best care to patients while advancing scientific discoveries that will shape the future of medicine.
