Undergraduate, MIT Physics & AI

I'm an undergraduate at MIT (Class of 2027), double-majoring in Physics (Course 8) and Artificial Intelligence (Course 6-4). Before MIT I spent a year studying physics at Peking University.

I work with Prof. Mingda Li in the MIT Quantum Measurement Group on machine learning for condensed matter physics, materials discovery, and defect engineering, supervised by Mouyang Cheng. I also work with Prof. Kaiming He on computer vision and generative modeling, supervised by Ming-Yang Deng.

Outside the lab, I enjoy long-distance running, classic films, linguistics, philosophy, vibe-coding projects, and Liu Cixin's novels.

Can God Be Proved to Exist? —Regarding Anselm’s Ontological Argument

Anselm’s ontological argument, presented in Proslogion II, seeks to demonstrate the existence of God solely by reflecting on the concept of God as "something than which nothing greater can be thought." I will analyze the argument, its premises, and the logical structure in this blog post.
