I am an Assistant Professor at the Department of Civil and Environmental Engineering, Northeastern University and the Associate Research Director of the Boston Area Research Initiative (BARI), Harvard University. I study the interplay between urban informatics and urban, infrastructure, and social resilience. My research focuses on two interrelated areas: human movement perturbation under the influence of natural and manmade disasters (collaborating with Georgia Tech and Virginia Tech), and geosocial networks in big cities (collaborating with Harvard University). The study of New Yorkers’ mobility during Hurricane Sandy is reported by CityLab, from The Atlantic.
Before joining in Northeastern, I was a postdoc fellow at the Department of Sociology, Harvard University. There, I found my research interests in studying social inequality and segregation using the “big data” from Twitter by working with Prof. Robert Sampson and Mario Small. I received my Ph.D. degree from the Department of Civil and Environmental Engineering at Virginia Tech. My advisor was Prof. John Taylor, director of the Network Dynamics lab. During my time at Virginia Tech, I was also the first Ph.D. Fellow at BioBuild, an interdisciplinary program, and a Via Teaching Fellow. I obtained my M.S. in Construction Management from Michigan State University and B.S. in Chemical Engineering from Tianjin University (China).
