Sean Qian is the Henry Posner, Anne Molloy, and Robert and Christine Pietrandrea Associate Professor jointly appointed at the Department of Civil and Environmental Engineering (major) and Heinz College of Information Systems and Public Policy (minor) at Carnegie Mellon University (CMU).

He directs the Mobility Data Analytics Center (MAC) at CMU. Qian’s research interest lies in large-scale dynamic network modeling and big data analytics for multi-modal transportation systems, in development of intelligent transportation systems (ITS) and in understanding infrastructure system interdependency.

His research has been supported by a number of public agencies and private firms, such as NSF, DOE, FHWA, Pennsylvania Department of Transportation (PennDOT), Pennsylvania Department of Community and Economic Development (DCED), IBM, Benedum Foundation, and Hillman Foundation.

Professor Qian serves an associate editor for Transportation Research Part C: Emerging Technologies, and an editorial board editor for Transportation Research Part B: Methodological, and is an active member of the Network Modeling Committee of Transportation Research Board.

He is the recipient of the NSF CAREER award in 2018 and Greenshields Prize from the Transportation Research Board in 2017. Qian was a postdoctoral researcher in the Department of Civil and Environmental Engineering at Stanford University from 2011 to 2013, and received his Ph.D. degree in civil engineering at the University of California, Davis in 2011 and his MS degree in statistics at Stanford University in 2012.
