I am currently a post doctoral researcher at the University of Toronto, working with the Intelligent Assistive Technologies and Systems Lab.

In September of 2007 I defended my thesis, which was titled "Machine Perception for Occupational Therapy" and was advised by Chris Atkeson. A copy can be found here. The work applied computer vision and haptic technologies to occupational therapy after stroke. Functional activity among stroke survivors was perceived by low cost devices and used to make automatic upper extremity assessments. The goal was to prototype a system that could make determinations of functional health accurately, continuously and cheaply, and in environments like the home.
