About:
I am recent PhD graduate in computer science at Yale, where I
was advised by James Aspnes.
During summer 2024, I will be a postdoc at IST Austria working
with Dan Alistarh and Krish Chatterjee.
Starting fall 2024, I will be a postdoc at SUTD in Singapore working with
Georgios Piliouras and Antonios Varvitsiotis.
My research interests are broadly at the intersection
of algorithms, theoretical machine learning,
and the foundations of data science, including:
- online learning, bandits, decision making, and games
- distributed algorithms, opinion dynamics,
and computation in multi-agent settings
- differentially private statistics and optimization
News:

In Summer 2022, I interned with the privacy-preserving machine learning
research group at Meta in NYC, where I collaborated with Sen Yuan
and Huanyu Zhang.
