About Me

I am a fourth-year PhD student in the Operations Research Department at Carnegie Mellon University. In particular, I am a student in the Algorithms, Combinatorics, and Optimization (ACO) Program. My advisor is Ben Moseley.

Previously, I obtained a MS in Computer Science and BS in Mathematics from Washington University in St. Louis, where I was advised by Brendan Juba.

Here is my CV. My e-mail is: rbz@andrew.cmu.edu.

Research Interests

Currently, my main interest is Optimization under Uncertainty including Online, Stochstic, and with Predictions. I am very interested in developing new techincal tools to understand and leverage Adaptivity in stochastic models. More broadly, I am interested in Approximation Algorithms and Combinatorial Optimization.
