Hello!

I am a Professor of Information and, by courtesy, Computer Science & Engineering at the University of Washington (UW). My field is human-computer interaction (HCI) with a focus on mobile and accessible computing. I am a co-founder of the cross-campus DUB Group and the MHCI+D degree. I also direct the ACE Lab and am an Associate Director and founding Co-Director Emeritus of the CREATE research center. My Ph.D. students come from information science and computer science.

I seek to scientifically understand people's experiences with interactive technologies, and to design, build, and evaluate better interaction techniques and systems, especially for people with disabilities. I have done extensive work in text entry, pointing, touch, and gesture; human performance measurement and modeling; HCI research and design methods; virtual reality; mobile computing; accessible computing; and human-centered A.I. Methodologically, I combine computer science, design, psychology, and statistics.

In 2010, I received an NSF CAREER award. In 2017, I was awarded the SIGCHI Social Impact Award. In 2019, I was inducted into the CHI Academy. In 2021, I was named an ACM Fellow for "contributions to human-computer interaction and accessible computing." In 2026, I received the SIGACCESS Award for Outstanding Contributions to Computing and Accessibility a lifetime achievement award. I have also received four 10-year lasting impact awards from: ASSETS 2019, ICMI 2022, UIST 2024, and ASSETS 2025.

I received my Ph.D. in 2006 from the Human-Computer Interaction Institute at Carnegie Mellon University, where my advisor was Brad Myers. I received my B.S. in Symbolic Systems in 1998 and my M.S. in Computer Science in 2000 from Stanford University, where my advisor was Terry Winograd.

I have also been an entrepreneur. In 2012, I co-founded AnswerDash—a SaaS company providing A.I.-powered context-sensitive help—where I was a venture-backed CEO for about three years. In 2020, AnswerDash was acquired by CloudEngage. My conversations with The New York Times and The Huffington Post capture some of my experiences as a startup CEO from academia.
