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.

In February 19-23, 2024 I visited the Université de Bourgogne in Dijon, invited by Pavao Mardešić and Dominique Sugny for the PhD defense of Gabriela Gutierrez-Guillen, and gave a talk on Maslov \(S^1\) bundles.
