I am a second-year PhD student in the Theory Group in the Computer Science Department at Carnegie Mellon University. I am fortunate to be advised by Pravesh Kothari and Ryan O'Donnell. I am broadly interested in theoretical computer science. Recently, I have been thinking about free probability, spectral graph theory, random graphs, and their applications in understanding average-case problems and quantum computing.
