Dr. Sankaranarayanan is the co-director of the Center for Assessment of Surgical Proficiency, which focuses on surgical simulation and surgical proficiency. Dr. Sankaranarayanan comes to the Department of Surgery from the Baylor University Medical Center in Dallas, where he was an assistant director for its Center for Evidence Based Simulation. 
Dr. Sankaranarayanan earned a Ph.D. in electrical engineering at the University of Washington in Seattle. He performed postdoctoral research at the Advanced Computational Research Laboratory of Rensselaer Polytechnic Institute in Troy, New York, which included studying virtual surgery simulation and medical robotics. He later served as an assistant professor and research scientist at the institute. Dr. Sankaranarayanan has also been an adjunct professor of electrical engineering at the University of Texas at Arlington and a clinical associate professor at the Texas A&M College of Medicine. 
Dr. Sankaranarayanan has conducted more than a dozen investigations that have been funded by the NIH, industry, and other sponsors. His work has included creating virtual reality simulators for surgery, using artificial intelligence to identify anatomy in laparoscopic procedures, and employing haptic devices via the internet. Dr. Sankaranarayanan’s findings have been published in Annals of Surgery, the American Journal of Surgery, and Surgical Endoscopy. His lap band simulator was a finalist for an “Immy” award at the Immersive Technology Summit. In addition, he has held key roles in the Society of American Gastrointestinal and Endoscopic Surgeons, including serving as the vice chair of its alternate funding task force and as a lead member of its fundamental use of surgical energy (FUSE) task force.
