Dr. Sharmila Dissanaike is the Professor and the Peter C. Canizaro Chair of Surgery at TTUHSC. She is the former Medical Director of the John A. Griswold Level 1 Trauma Center and the Assistant Director of the Timothy J. Harnar Burn Center at UMC. She is active in clinical surgery, with a focus on critical care, trauma and burns. Her commitment to promoting the highest-quality surgical care nationwide is evident in her role as Chair of the Verification Committee for the American Burn Association, and the American College of Surgeons Committee on Trauma.

Dr. Dissanaike has won numerous awards for clinical performance and academic achievement, as well as teaching awards from surgery residents and medical students. She serves on the Ethics Committee of the American College of Surgeons where she developed Guidelines for the Ethical Use of Social Media, and is former Chair of the Ethics Committee for the American Burn Association. She has a strong interest in promoting clinical research, and serves as the School of Medicine representative to the TTUHSC Clinical Research Institute. Her own research interests focus on trauma and burns, and she was the Founding Director of the Burn Center for Research Excellence (BCORE). She has over 80 peer reviewed publications, over 150 competitive national and international presentations and many invited lectureships. She has served as principal investigator or co-investigator on multiple research projects which have together received approximately $2.5 million in funding. She has served as a research mentor for over 140 residents, medical students, graduate and undergraduate students, thus helping to increase interest in innovation, scientific method and critical thinking among the next generation of physician leaders. Her current interests include developing novel systems of healthcare delivery, such as a shift-model for trauma and emergency general surgery, that provide quality patient care while allowing surgeon wellness and fostering opportunities for career development as an academic surgeon.

My outpatient clinical interests focus on skin and soft tissue reconstruction for defects arising from large wounds or cancers, resection of redundant tissue such as excessive fat after weight loss, skin cancers, and hernia repair. I also perform routine general surgery, and have an inpatient practice focused on trauma, burns and critical care.

Research interests include all aspects of trauma, burns and the management of critically ill patients. I have a focus on injury prevention and the relationship between substance abuse and injury. I also have an interest in nutrition and surgical healing.  Director of the Burn Center of Research Excellence (BCoRE).
