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 research centers on the precision measurement of neutrino oscillation parameters through detector calibration, low-background control, neutrino interaction simulation, and systematic uncertainty modeling, developed across the Daya Bay Reactor Neutrino Experiment, the Jinping Neutrino Experiment, and, most recently, the Jiangmen Underground Neutrino Observatory (JUNO), where I contribute to the determination of the neutrino mass ordering. I am actively recruiting master's 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.
