My research interest lies in urban systems. My current research focuses on daily travel behavior. First, I look at what activities people do in their daily lives, how is this related to characteristics of individuals, and how do different built environments with different urban opportunities facilitate or constrain people’s activity choices? Second, I’m interested in the associations among various daily activities and in identifying distinct lifestyles. Further, I intend to examine the connection of lifestyles with characteristics of individual and built environment. Third, I would like to examine the characteristics of travel behavior associated with these activities. More specifically, I try to figure out what are people’s activity spaces reflected in those travel 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.
I am specifically interested in the applications of various tools such as statistics, spatial modeling, social network analysis, and machine learning in solving problems and discovering underlying patterns of the world.
