About

Experimental neutrino physics for fundamental questions

I received my PhD from Tsinghua University in 2022 and served as a Postdoctoral Research Assistant there through 2025 before joining Hunan University. My undergraduate training was at Huazhong University of Science and Technology.

My current work spans detector calibration, low-background control, neutrino interaction simulation, and systematic uncertainty modeling — with contributions to the Daya Bay Reactor Neutrino Experiment and the Jinping Neutrino Experiment. I am actively recruiting master students and welcome inquiries from prospective collaborators at [email protected].

Research

Three directions

Reactor neutrino oscillation

Precision measurements of the mixing angle θ₁₃ and the mass-squared splitting, including hydrogen-capture analyses at Daya Bay.

See this direction →

Low-background detector systems

Calibration workflows, stability control, and systematic mitigation for ultra-low-background operation in deep underground laboratories.

See detector work →

Underground muon physics

Deep-lab measurements of cosmic-ray muons and cosmogenic neutrons, informing both hadronic interaction models and astroparticle physics.
