About

Greetings! My name is Chenfeng Xiong.

I am an Assistant Research Professor at the Department of Civil and Environmental Engineering, University of Maryland, College Park, and am an affiliated Assistant Professor at the Shock Trauma Center, School of Medicine, University of Maryland, Baltimore. I earned my Ph.D. in Transportation Engineering from the University of Maryland in 2015. I earned M.A. in Economics and M.S. in Transportation Engineering from the University of Maryland in 2013 and 2011, respectively. My Bachelor's degree with a major in Civil Engineering was awarded at Tsinghua University, Beijing in June 2009. I am interested in understanding the fundamentals of transportation systems, including travelers' choices, mobility, safety, health, and economics. More about me can be found in this personal webpage.

Research

Transportation Systems

I work on transportation systems models and simulation to replicate the real-world human mobility and adaptations, and predict future landscape of the transportation systems and beyond.

Data-Driven Modeling

Big data and data-driven approach can be applied to solve often complex problems. I am interested in advanced mathematical and statistical methods to extract empirical evidences for problem-solving.

Interdisciplinary Perspectives

Mobility is a major pillar of people's everyday life. I am interested in exploring multidisciplinary topics cutting across transportation economics, safety, and health that are fundamental to quality of life.
