My interests include public transportation, transportation planning, and intelligent transportation systems. My research focuses on understanding how new information and communication technologies can be used to improve transportation systems. Recently, I have conducted studies to evaluate the impacts of real-time transit information on passenger behavior in New York City, Tampa and Boston. Additionally, I am currently collaborating with the smartphone app Transit to study user patterns, including recent studies of transit information use and intercity travel patterns. I also conduct research on mobile ticketing applications for transit, such as the ferry in New York City and the commuter rail in Boston, and I have studied open payment fare collection systems, including in Chicago and London.
I have a PhD in Civil Engineering from Georgia Institute of Technology, dual Master of Science degrees in Transportation and Technology Policy from Massachusetts Institute of Technology, and a Bachelor of Science in Mechanical Engineering from Johns Hopkins University.
