About me

Hi! I am a senior undergraduate student majoring in Computer Science & Mathematics in The Hong Kong University of Science and Technology (HKUST). My research interest lies in deep learning theory, providing theory to understand and explain behaviors of modern deep learning algorithms. Recently, I’ve been working on investigating empirically how LLM works. I’ve written some notes on what I’ve learned, so feel free to check them out!

I am interested in applying for PhD position in Computer Science / Statistics / Operations Research starting in 2025 Fall, and I like chatting with like-minded people so feel free to connect if you share similar research interest with me!

I am very fortunate to be mentored by Wei Hu at Michigan and Yiping Lu at Northwestern who always provide support and suggestions. I am also very grateful to Tong Zhang (previously at HKUST) for giving me opportunity to start my research in my sophomore year.

Education

BSc in Computer Science & Mathematics, Hong Kong University of Science and Technology, 2025 (Expected)
Exchange (Computer Science), École Polytechnique Fédérale de Lausanne, 2024 Spring

Research experience

July 2024 ~ Ongoing: Research Internship
- Supervised under Professor Wei Hu @ Michigan
- Working on understanding in-context learning mechanism using clean and controlled setting
July 2023 ~ Ongoing: Remote Collaboration
- Supervised under Professor Yiping Lu @ Northwestern
- Worked on benign overfitting for PINN, and had a first-authored paper under review
- This work has an interesting finding that with smooth enough inductive bias, overparametrized kernel interpolator can obtain optimal convergence rate.
- Organized the Deep Learning Theory Reading Group inside the research group
Oct 2022 ~ Nov 2023: Undergraduate Research Opportunities Program (UROP) @ HKUST
- Supervised under Professor Tong Zhang @ HKUST
- Paper accepted to ICLR2024 as coauthor
- This work has an interesting finding that ensemble of models with spurious features can improve its performance, which is contrary to common belief on OOD that models should maintain invariant features and disgard spurious features like IRM.
- (Here begins my research journey! Very thankful to Yong Lin, Yifan Hao and Lu Tan for guiding me)
