On Wednesday, June 19, 2024 I am giving a talk on integrable Hamiltonian systems at the Department of Mathematics of Nanjing University, hosted by Professor Wei Cheng.

On Thursday, April 25, 2024 I am organizing a mini-workshop on Dynamics and Physics at Duke Kunshan University.

Topological Data Analysis (TDA) has proved to be a very powerful tool for the analysis of the structure of the Cosmic Web. In our recent work “Topological bias: how haloes trace structural patterns in the cosmic web”, we report a remarkable linear relationship between halo masses and topology.
