My homepage will soon be revised to reflect my current research more appropriately.

Welcome to my home page. I'm a PhD candidate at the Laboratory for Perceptual Robotics at the University of Massachusetts Amherst under the supervision of Professor Roderic A. Grupen. Other professors that I frequently collaborate with include Shlomo Zilberstein from School of Computer Science and Yu-Kyong Choe from Department of Communication Disorders at the University of Massachusetts Amherst. Before joining UMass, I conducted my MS at Stanford University and BS at Yonsei University.

My research focus is to assist domain experts in overcoming the challenges of contemporary practices and achieving better performance in their tasks. The primary project is to write individualized therapy programs for post-stroke patients who do not have easy access to experienced therapists. Towards that end, I proposed and have been investigating a framework and computational models that can be used standalone or along with physically/socially assistive robots. The project involves 1) finding structures in therapeutic tasks which allows decision making in a task space, 2) devising and testing the feasibility of remote therapies (using robots and potentially games), 3) modeling the motor performance of an individual patient and the target selection model of a therapist in the defined task space.
