Paul G. Allen School of Computer Science & Engineering at the
University of Washington,
where I direct the
Mobile & Accessible Design Lab.
I am a founding member of the
DUB Group and the
Master of Human-Computer Interaction & Design
My Ph.D. students
come primarily from
information science and
My research seeks to
scientifically understand people's interactions with computers and information, and
to improve those interactions through design and engineering,
especially for people with disabilities.
My specific research topics include
input & interaction techniques,
human performance measurement & modeling,
HCI research & design methods,
mobile computing, and
My work has received
21 paper awards,
7 best papers and 8 honorable mentions from ACM's flagship
For my work on Ability-Based Design, I received the
2017 ACM SIGCHI Social Impact Award.
Some of my notable projects are
the $-family gesture recognizers,
the end-user elicitation design method,
the Slide Rule design for accessible touchscreen gestures,
ARTool for nonparametric factorial statistical analyses,
and the EdgeWrite text entry system.
I have also been a tech entrepreneur and startup CEO. In this role, I was interviewed by
