I am a senior research associate in University of Oxford, working with Leslie Ann Goldberg.
In 2024, I graduated from Penn State where I was fortunately advised by Antonio Blanca.
Before Penn State, I enjoyed building cloud products for Amazon Web Services.
I am attracted to fun puzzles in mathematics and algorithms, and I work in the intersection of theoretical computer science, probability theory, and statistical physics. Main themes of my research interests have been sampling via Markov chains, decentralized learning, and stochastic processes on network.
