I regularly publish in journals and conference proceedings, including the International Journal of Human-Computer Interaction, ACM Transactions on Computer-Human Interaction, ACM Transactions on Accessible Computing, Government Information Quarterly, Behaviour and Information Technology, Journal of Usability Studies, and Interacting with Computers. I also regularly teach courses on human-computer interaction, web usability, web accessibility, and Management Information Systems. I have published 6 books. The three best-known books are: Research Methods in Human-Computer Interaction, published by John Wiley and Sons in 2010, Web Usability: A User-Centered Design Approach (published by Addison-Wesley) and Universal Usability: Designing Computer Interfaces for Diverse User Populations , a book that I edited, which is available from John Wiley and Sons. I currently serve on the editorial boards of Interacting with Computers and Universal Access in the Information Society and I am the forum editor for public policy in Interactions Magazine. I serve on the executive board of the Friends of the Maryland Library for the Blind and Physically Handicapped and I am an affiliate researcher at the Information Policy and Access Center at the University of Maryland College Park.
My research has been highlighted in articles in the Baltimore Sun, Wall Street Journal, Louisville Courier-Journal, Minneapolis Star-Tribune, Braille Monitor, and stories on National Public Radio, WAMU-FM, WCBM-FM, and WMAR-TV. I have served on program committees for the SIGCHI, ASSETS, SIGDOC, INTERACT, and HCII conferences. My research has been funded by the National Science Foundation, and I am also available for consulting work.
