About me

I am an Assistant Professor of Operations Management at the Krannert School of Management, Purdue University. I joined Krannert in Janurary 2014.

I obtained my Ph.D. degree from the School of Industrial and Systems Engineering at Georgia Institute of Technology in December 2013. I received my B.Eng. in Applied Mathematics and Mechanics and B.A. in Economics (double major) from Peking University, China, in June 2007. My Ph.D. advisors are Jim Dai and Pinar Keskinocak. Here is a copy of my Ph.D. thesis [pdf].


My research focuses on building data-driven, high fidelity models and developing analytical methods to support decisions making under uncertainty in various healthcare systems.

Currently I am studying patient flow models for improving hospital operations and patient outcomes. In the past, I have worked on spatial-temporal epidemic models to study the course of influenza pandemic.

I strive to develop high impact research and tackle real-world problems. I have been collaborating with practitioners and faculty members from different healthcare organizations, and worked extensively with large-scale data sets from hospitals in the US and Singapore.
