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