  • My research program focuses on theoretical and applied issues in visual perception, and human factors. My primary interests include (a) the perception of collision, motion, and depth with applications to transportation (e.g., driving and aviation), health care (minimally-invasive surgery), military (e.g., night vision goggles), and sport (e.g., umpiring), (b) human factors in health care (e.g., patient safety), (c) performance in nursing (e.g., medication administration), and (d) tele-mental health.
