👋 Hi there, I’m Jingbo — a CNRS postdoctoral researcher passionate about Geometric Analysis and General Relativity

🗼 I will be a CNRS postdoctoral researcher at Sorbonne University in Paris, starting from Fall 2025.

🎓 I received my PhD in Mathematics from Columbia University, where I was fortunate to be advised by
Prof. Mu-Tao Wang and Prof. Elena Giorgi.

🏫 I completed my undergraduate studies at The Hong Kong University of Science and Technology (HKUST), mentored by
Prof. Frederick Fong.


🧠 Research Interests

I work at the intersection of differential geometry, partial differential equations, and general relativity, with a focus on the geometry of black holes and related nonlinear problems.
