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 public 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. I am also actively working in the area of mobile ticketing applications for transit, including recent studies of the ferry in New York City, the commuter rail in Boston, and the bus system in Nassau County. Similarly, 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.
