Beyond knowing how things are,
There is no other understanding.

A Song on the Six Perfections, Milarepa

I am an associate professor in the School of Operations Research and Information Engineering (ORIE) at Cornell, as well as a field member in Departments of Computer Science, ECE, and the Center for Applied Mathematics.

I work on topics at the intersection of data-driven decision-making and stochastic control, economics and computation, and large-scale network algorithms. Some of my current research interests include:

• New data-driven approaches for online decision-making [seminar]
• Non-monetary mechanisms and information design [seminar]
• Equity and fairness in online decision-making [seminar]
• Stochastic coupling techniques in control (tutorial: [part 1], [part 2])

Prior to Cornell, I received my PhD from the ECE Department at UT Austin, and was a postdoctoral researcher at Stanford MS&E. I also served as technical consultant at Lyft in 2014-18, where I helped develop and implement Lyft’s primetime pricing; the following tutorial and book chapter give an overview of my work on ridesharing platforms.

I am currently on sabbatical at the Simons Institute in Berkeley as a co-organizer of the program on Data-Driven Decision-Making.
