Research

Smart tools: These are instrumented surgical tools which enable quantitative techniques in the operating room.
Surgical Robotics: This includes custom built robots that automate access to all patient surgical sites and the operating room environment, extracting meaningful information such as procedural markers or surgical skill from the sensor streams of the robot, and creating new algorithms and tools that enable novel surgical procedures.
Surgical Simulation: In collaboration with the center for research in education and surgical training (CREST), we investigate novel techniques for training surgical procedures in virtual reality or realistic mock tissues.
Surgical Genome Project: In collaboration with the University of Washington, this project aims to create a large, open database of surgical procedures including tool tracking, operative video, and a variety of sensors inputs. The aim is to provide a common resource for researchers to investigate surgical behavior, design requirements, and to develop and compare analysis algorithms in a repeatable way.
