ABOUT me
I am a Professor in the Department of Computer Science at the University of Toronto. I received my Bachelor degree in Computer Engineering from the School of Electrical and Computer Engineering and my Ph.D. degree in Computer Science from the College of Computing at the Georgia Institute of Technology.

RESEARCH interests
My research lies at the intersection of Human–Computer Interaction (HCI) and ubiquitous/pervasive computing, with an increasing focus on the design and evaluation of health and assistive technologies. In particular, I investigate how interactive mobile, wearable, and ubiquitous computing systems can support health, well-being, and accessibility across diverse populations (e.g., older adults, people with disabilities). A central goal of my work is to design user-centered interfaces and systems that are usable, acceptable, and respectful of privacy, autonomy, and social context. I blend technical system development with empirical evaluation in real-world or ecologically valid health-care settings, integrating usability, accessibility, ethics, and user-experience perspectives to create interactive health solutions that are both effective and socially appropriate.
