My research interests include urban travel behavior, urban networks, and urban modeling and simulation. My current research focuses on daily travel behavior in the Detroit region. I look at what activities people do in their daily lives, how is this related to characteristics of individuals, and how different built environments with varying levels of access to urban opportunities facilitate or constrain people’s activity choices. Also, I intend to examine the characteristics of travel behavior associated with these activities. In particular, I try to figure out what are people’s activity spaces reflected in those activities. My research goal is to provide a deeper understanding of urban travel in distressed urban regions and assist in the achievement of efficiency and social equity and inclusion. In my research, I am specifically interested in the application of quantitative tools, such as statistics, spatial modeling, social network analysis, and machine learning, in modeling urban patterns and dynamics.
