📚 My Research

I am a theoretical physicist, eager to learn about the laws of nature.

I apply various quantitative methods to comprehensively investigate how the fundamental physics laws that governs the motion of subatomic particles can shape our universe.

I write code to reproduce the cosmos on huge computer clusters —- a world model not driven by data, but from physics.

I am curious to learn and explore the world beyond my main research area. How to build world model from physics for AI? How patterns merge in complex systems.
