My latest study is a collaboration with Kayleigh Campbell that analyzes the impact of bikesharing on bus ridership in New York City. CityLab covered the research, and the full text of the study can be found here.
My research interests include public transportation, transportation planning, transportation policy, and intelligent 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.
