I am an assistant professor in the Department of Information Systems at the University of Maryland, Baltimore County. With Amy Hurst, I co-direct the UMBC Prototyping and Design Lab.

My primary research interests are accessible user interfaces and mobile human-computer interaction. My work explores ways to make mobile devices easier to use, especially for people with disabilities and people in distracting environments.
