I am a Ph.D. candidate in the Department of Computer Science, University of Maryland, College Park. I work with Prof. Jon Froehlich in the Human-Computer Interaction Lab.

My research focuses on design of systems to collect and deliver information about accessibility of streets and sidewalks that help people with mobility impairments. Using geo-tagged street-level imagery like Google Street View as data source, we locate sidewalk accessibility problems with crowdsourcing and computer vision technologies.
