Guru, MD, director of robotic surgery at Roswell Park Cancer Institute (RPCI), and Thenkurussi "Kesh" Kesavadas, PhD, director of the Virtual Reality Lab and a professor of mechanical and aerospace engineering at the University at Buffalo (UB), created Hands-on Surgical Training (HoST) to harness the didactic potential of their proprietary Robotic Surgical Simulator, or RoSS.
