I am currently a research fellow working with Prof. Brian Denton at The University of Michigan. My primary research interests lie at the intersection of operations research and healthcare. I am particularly interested in stochastic programming, dynamic programming, and data-driven optimization. The overarching goal of my research agenda is to develop the computational methods needed to help organize healthcare operations and improve precision medicine.

I am also greatly honored to work with Prof. Xiaolan Xie on health care scheduling during my Ph.D studies. To find out more about my research interests, please go to the "Research" section below.

I will join the Operations Management group at the School of Management, Zhejiang University as a ZJU 100-Young professor (tenure-tracking assistant professor) starting from fall 2019.
