Welcome!

I am a Professor of human-computer interaction (HCI) in The Information School and, by courtesy, in the Paul G. Allen School of Computer Science & Engineering at the University of Washington, where I direct the ACE Lab and co-direct the CREATE Center. I am also a founding member of the DUB Group and the MHCI+D degree. My Ph.D. students come from information science and computer science.

My research seeks to scientifically understand people's experiences of computers and information, and to improve those experiences by inventing and evaluating new interactive technologies, especially for people with disabilities. My specific research topics include input and interaction techniques, human performance measurement and modeling, HCI research and design methods, mobile computing, and accessible computing.

For my contributions to accessible computing, I received the 2017 SIGCHI Social Impact Award and the 2019 SIGACCESS ASSETS Paper Impact Award. In 2019, I was inducted into the prestigious CHI Academy.

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, the Pointing Magnifier 2 assistive pointing and visual aid, and the versatile EdgeWrite text entry system.

I have also been an entrepreneur. In 2012, I co-founded AnswerDash, where I was a venture-backed C.E.O. 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 founder.
