RESEARCH [Mentorships] [Publications]
Research areas include computer vision, computer integrated surgery, human-computer interaction, robotics, artificial intelligence, and statistical analysis.

Language of Surgery - Investigating the existence of a structured language in surgery through the use of statistical processing, computer vision, robotic surgery, speech processing, and linguistics. The motivation is to create benchmarks for surgical skill evaluation, develop methods for better surgical training, and to automate the documentation of surgeries for libraries.
Topics: statistics, computer vision, speech processing, linguistics
Funding: (2005-present, NSF main award, IREE supplement, and Link fellowship funded)
Human-Machine Collaborative Systems - Developing techniques for designing systems that amplify or assist human physical capabilities when performing tasks that require learned skills, judgement and dexterity. Robot-assisted retinal vein cannulation combined robotics, virtual fixtures, and computer vision to help reduce the tremors of the surgeon and improve accuracy.
Topics: computer vision, robotics, virtual fixtures, mechanical design
Funding: (2003-2004, NSF main award funded)
Virtual Fixtures and Robotics - Investigating the portability and applicability of virtual fixtures across medical and manufacturing tasks. A commercially available motion platform by Invenios is used for this research.
Topics: robotics, virtual fixtures, mechanical design
Funding: (2004-2005, NSF SBIR funded)
