About Me
I am a third-year PhD student in computer and information science at the University of Pennsylvania, advised by Jacob Gardner.
Previously, I completed my MMath degree in computer science at the University of Waterloo, where I worked on trustworthy machine learning with Yaoliang Yu.
I did my undergraduate at Nanjing University.
I am interested in machine learning and optimization.
My recent work focuses on scaling up computation in probabilistic machine learning.
Specifically, I work on Gaussian processes, variational inference, and Bayesian optimization.
I have side interests in convex optimization and deep generative modeling.

I have reviewed (or will review) for the following conferences: AAAI 2021, AISTATS 2021, ICML 2023, NeurIPS 2023, ICLR 2024, AISTATS 2024, ICML 2024.
I write notes when I have time.
My writing pet peeves
- Leave latex compilation errors unfixed in overleaf. It is a felony.
- Orphans.
- It's UPenn, not Upenn.
A useful website calculating (an upper bound of) the Erdős number.
