My name is Sean Z. Qian. Qian reads like [Chien], or if you insist trying its perfect pronunciation.

I am Henry Posner, Anne Molloy, and Robert and Christine Pietrandrea Associate Professor of Civil Engineering, jointly appointed at the Department of Civil and Environmental Engineering (major) and Heinz College (minor) at Carnegie Mellon University. I direct the Mobility Data Analytics Center (MAC). I also hold a Courtesy Associate Professor appointment at the Department of Electrical and Computer Engineering.

My research interests lie in the integration and optimization of civil infrastructure systems. The primary focus is to manage an aging and overcrowded infrastructure and cyber-physical-social systems, and to build a sustainable and resilient infrastructure network. I have been developing optimization and statistical models of infrastructure system management by applying theories of AI, network flow and economics.

I did my post-doctoral research at the Department of Civil and Environmental Engineering, Stanford University. I received my PhD degree in Civil Engineering and Institute of Transportation Studies at UC Davis, and my Bachelor's and Master's degrees in Civil Engineering with the focus on Transportation from Tsinghua University, Beijing.

I am always open to working with highly motivated students who have strong quantitative background. Please send me an email if you are interested in the intersection of cyber, infrastructure and social systems, and you are enthusiastic about programming and mathematical modeling. Currently, I am looking for 1-2 Ph.D. students entering Spring 2022, and 1-2 postdoctoral researchers (position available now).

My research interests include:

  • Dynamic network modeling (routing, simulation and optimization)
  • Intelligent transportation system (ITS)
  • Applications of ML/AI in infrastructure management
  • Infrastructure resilience
  • Urban systems interdependency
  • Multi-modal transportation
  • Parking management
  • Transportation economics
  • Traffic operations
