I am an Associate Professor in the
Information School and, by courtesy, in
Computer Science & Engineering at the
University of Washington.
I chair the
Master of Human-Computer Interaction & Design
program and direct the
Mobile & Accessible Design Lab.
I am a founding member of the
My field is human-computer interaction (HCI).
My research seeks to scientifically understand people's interactions with computers and information,
and to improve those interactions through design and engineering,
particularly for people with disabilities.
My specific research topics include:
(i) input techniques (text entry, pointing, touch, gesture, voice, gaze),
(ii) mobile and tabletop user interfaces,
(iii) human performance with computers,
(iv) HCI research and design methods, and
(v) accessible computing for people with disabilities.
My work has received 18 paper awards, including
6 best papers and 7 honorable mentions from CHI.
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 method.
I am currently developing
a design approach in which the human abilities required to operate a technology are questioned,
and systems are made operable by and adaptable to alternative abilities.
My Ph.D. students
come primarily from UW Ph.D. programs in
information science and
I am also an entrepreneur, having co-founded
AnswerDash, a company that provides context-sensitive help
to websites. I was AnswerDash's
venture-backed CEO from September 2012 – May 2015, its
Chief Scientist from May – December 2015, and its
Chief Experience Officer (CXO) thereafter. I have also worked in other
industry jobs and occasionally serve as an
expert witness on intellectual property matters.
