I currently serve on the editorial board of Interacting with Computers and I have previously served on the editorial board of Universal Access in the Information Society. I am currently the forum editor for public policy in Interactions Magazine, and I also serve on the executive board of the Friends of the Maryland Library for the Blind and Physically Handicapped .
During the 2012-2013 year, I was a Fellow at the Radcliffe Institute for Advanced Study at Harvard University, where I collaborated with the Harvard Law School Project on Disability, and I am also 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.
