I am currently a postdoc in the Operations Research Department at Carnegie Mellon University. I graduated in May 2023 from the same department through the the Algorithms, Combinatorics, and Optimization (ACO) Program, where I was advised by Ben Moseley. My thesis On Combinatorial and Stochastic Optimization won the 2023 Gerald L. Thompson Doctoral Dissertation Award in Management Science.

In Summer 2022, I was an intern at Microsoft Research Redmond in the Cloud Operations Research (CORE) group, where my mentor was Konstantina Mellou.

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. Here is my Google Scholar and DBLP.

I am on the job market for both academia and research positions in industry.

Research Interests

I am broadly interested in algorithm design with a focus on optimization under uncertainty. I design provably good algorithms for fundamental optimization problems in areas such as scheduling, resource allocation, and data analysis.

Recently, I am excited about stochastic combinatorial optimization, where we only have distributional information about the input. In this setting, I am thinking about new algorithms, hardness of approximation, adaptivity gaps, and imperfect information.
