About me:

I am the Regina Pitaro Associate Professor of Business in the Decision, Risk, and Operations Division at Columbia Business School. My primary research interests are at the interface of applied probability and service operations management. My current research focuses on developing data-driven stochastic modeling to improve patient flow in healthcare delivery systems. I also develop efficient simulation algorithms to facilitate better decision-making in complex stochastic systems.


I did my undergraduate in Actuarial Science at Hong Kong University and received my Ph.D. in Operations Research from Columbia University. Before joining Columbia Business School, I was an Assistant Professor at Northwestern University.



I am co-organizing an online-seminar series: Women in Data Science and Mathematics. More information can be found here.
