About me

I am now a visiting fellow of the Strong Group at Niels Bohr Institute. I graduated from School of Physics at Peking University and got my Bachelor’s degree in July 2025.

My research is mainly about black hole perturbation theory and its various applications, including waveform modeling of different gravitational wave events (e.g. BBH, EMRI, b-EMRI), quasi-normal modes of black holes, and scattering of gravitational wave by black holes.

GSN 0.9.0 is getting the ISEM branch.

GeneralizedSasakiNakamura.jl now has ISEM machinery for Teukolsky point-particle flux mode summation: radial Teukolsky solves, generalized Sasaki-Nakamura solves, and a shared Y variable convention tied to the two PRD projects on Sasaki-Nakamura waveforms and near-horizon Kerr perturbations.

KerrGeodesics.jl 0.3.0 supports plunge orbits.

The package now goes beyond bound Kerr geodesics and can generate plunge trajectories for waveform and flux pipelines.
