About Me

Hello and Xin chao! I am a cosmologist interested in tracking the growth of large-scale structure across the history of the Universe. I model and combine different probes of cosmic structure, from counting galaxies to measuring galaxy alignment and weighing galaxy clusters.

My work has led to the first 4-sigma evidence for a late-time suppression in the growth of large-scale structure, highlighted in Physical Review Letters and covered by Scientific American and New Scientist. I also developed a field-level Bayesian inference framework for galaxy surveys, a line of work that led to a second Physical Review Letters paper and the 2024 Buchalter Cosmology Prize.

I am currently a Kavli IPMU Fellow at the Kavli Institute for the Physics and Mathematics of the Universe, University of Tokyo. Before joining IPMU, I was a Leinweber Fellow at the University of Michigan, and before that I completed my PhD at the Max Planck Institute for Astrophysics.
