Biography

Qie He is an assistant professor at the Department of Industrial and Systems Engineering, University of Minnesota. His primary research interests are to develop analytics and optimization models, algorithms, and software to improve public transportation and logistics. He is also interested in optimal control theory with its application in cancer treatment. The analytics tools his group developed have been used by Metro Transit, the primary public transportation service provider in Minnesota, and the Transportation Department of Hennepin County, the largest county in Minnesota by population. He has been a faculty scholar at the Center for Transportation Studies at the University of Minnesota since 2017. 

Professor He received a Ph.D. in Industrial Engineering from Georgia Tech and an M.S. in Control Science and Engineering and a B.S. in Automation, both from Tsinghua University.

Research Interests

My main research goal is to improve the service quality and efficiency of transportation and healthcare. Specifically, I develop prediction and optimization algorithms to help public transportation agencies improve their planning and operational practices; I develop efficient algorithms with performance guarantee to solve large-scale routing and scheduling problems faced daily by logistics and e-retail companies; I collaborate with doctors and applied mathematicians to discover new cancer treatment plans. The central theme of my research is to build new models, algorithms, and practical tools to bridge the gap between massive available data and complex decision making.

The projects I have worked on include exact algorithms for various vehicle routing and scheduling problems (for reducing energy consumption, for on-demand delivery system, and for restoring power networks), public transit workforce optimization, data-driven fleet management, capacity design and information release of parking systems, design of on-demand delivery systems, and personalized cancer treatment.
