Biography

I am currently a Full Professor and Andre Meyer Faculty Fellow at the Department of Technology, Operations, and Statistics at Stern School of Business at New York University. I also hold affiliated faculty positions at Courant Institute of Mathematical Sciences and Center for Data Science.

In 2021–2023, I contributed two years as a principal scientist at Amazon Ads, where I spearheaded a science team to advance forecasting and delivery systems in digital advertising. I also collaborated with industry giants such as Google, Meta, Adobe, JP Morgan, and Bloomberg have addressed a range of technical and business challenges, and obtained outstanding faculty research awards from each.

Before joining NYU Stern, I did a postdoc with Professor Michael I. Jordan at the University of California, Berkeley. I earned my doctoral degree from Carnegie Mellon University. Before that, I obtained my master of science in Industry Administration (Operations Research) from the ACO program in the Tepper School of Business at Carnegie Mellon.
