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 average case problems and spectral properties of random graphs.
