I am a fifth-year graduate student in the theory of computation group at Harvard University, advised by Boaz Barak. I will join IDEAL as postdoc starting in Fall 2023.
My research focuses on the computational complexity of statistical inference, lying at the intersection of theoretical computer science, statistics, probability and data science. Recently, I have been investigating the phenomenon of information-computation gaps in the context of discrepancy theory, random CSPs, estimating parameters of high-dimensional, heavy-tailed distributions, and differential privacy.
My graduate studies are supported by an NSF Graduate Fellowship.
