She received her Ph.D. (2005) in Civil and Environmental Engineering from the University of California, Berkeley. Her research and teaching interests are in traffic flow theory and operations, Intelligent Transportation Systems applications, and traffic operational impacts on environment and safety. Her research goals are to 1) better understand the fundamental nature of traffic flow through observation, experimentation and the application of quantitative (statistical) methods, 2) examine the environmental and safety impact of traffic flow phenomena, and 3) apply the knowledge in developing traffic theories and control strategies through applications of ITS.
