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