Welcome to my webpage!

I am assistant professor in Decision, Risk and Operations at the Columbia Business School. My research sits at the intersection of Industrial Organization and Operations Research. 

Before joining CBS, I earned both Bachelor and Master of Science degrees in Economics from Bocconi University, completed a Ph.D. in Economics at Harvard University in 2021, and spent a year as a Postdoctoral Research Associate in the Department of Economics at Princeton University.

At CBS I teach the core MBA course in Operations Management and core Ph.D. course in Econometrics and Statistical Inference.
