I am a postdoc in City University of Hong Kong studying black hole perturbation theory and cosmology. I earned my PhD in physics from Rice University in 2024, where I worked on gravitational particle production and cosmological perturbation theory. Currently, I am interested in nonlinear effects in black hole ringdowns, such as power law tails in GW waveforms. I am also interested in various numerical methods, including novel forms of simulations and GPU-based methods.
