Headshot of Richard wearing a Google Glass Hi! I'm Richard.

Currently a PhD student in Computer Science & Engineering at the University of Washington (UW). Previously an intern on the EPIC and Ability teams at Microsoft Research, and was a research scholar at Google [x] and Google Research. Check out some of the cool and things I've worked on, and feel free to say hi :).

Research Overview

My research interests lie at the intersection of artificial intelligence, embedded systems, and human-computer interaction, materializing in the form of wearable and ubiquitous computers. I work with James Fogarty and Shwetak Patel (in the Ubicomp Lab) among many other amazing collaborators across multiple departments at the University of Washington on a variety of topics ranging from mobile health applications to novel user interfaces. I publish this work at academic venues such as the Interactive, Mobile, Wearable and Ubiquitous Technologies (IMWUT) journal and at the Conference on Human Factors in Computing Systems (CHI); see below for a complete list of publications.
