About me

Hi! I am a first-year PhD student at the University of Pennsylvania, advised by Surbhi Goel (Computer Science) and Enric Boix-Adsera (Wharton Statistics & Data Science). I received my Bachelor’s degree in Computer Science & Mathematics from the Hong Kong University of Science and Technology (HKUST) in 2025. My research is supported by AWS Asset Fellowship at Penn.

My research interests lie in the theory and empirical science of deep learning and LLMs. On the theoretical side, I study fundamental principles of learning and scaling, with an emphasis on training dynamics and expressiveness. On the empirical side, I investigate the model’s behavior through controlled experiments. I am also interested in mechanistic interpretability as a way to uncover how neural networks represent and manipulate information.

Overall, I see myself as both a theorist and an experimentalist, driven by the goal of opening the black box of neural networks and LLMs from multiple complementary angles.

Outside of research, I am (was) running a popular science channel with over 34K subscribers and 1.7 million total views.
