Omar Alrabiah

I’m a second-year graduate student at UC Berkeley and part of Berkeley’s Theory Group. I am very fortunate to be advised by Venkatesan Guruswami. Previously, I was an undergraduate student at Carnegie Mellon University, where I majored in mathematics with an additional major in computer science and graduated with University Honors and Mellon College of Science Research Honors.

My primary interests lie in coding theory and pseudorandomness. I care about constructing useful algebraic objects (or showing that they cannot exist).
