Symposium for Henk Broer’s 75th Birthday

October 16-21, 2025 I will be back in Groningen for the Symposium on the Occasion of Henk Broer’s 75th Birthday. In the symposium I give a presentation on Integrable Hamiltonian Systems, a topic on which I have worked together with Henk.

Conference on Integrable Systems and Related Areas

In the week June 23-27, 2025 I am attending the conference Integrable Systems and Related Areas in CGP-IBS POSTECH, where I give a presentation on Maslov S1 bundles.

Visit University of Catania

In the week November 18-22, 2024 I am visiting the University of Catania, hosted by Professor Andrea Giacobbe.

Talk at Nanjing University

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.

Mini-Workshop on Dynamics and Physics

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

Paper on Topological Bias in the Cosmic Web

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.

Visit Université de Bourgogne and PhD defense Gabriela Gutierrez-Guillen

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 S1 bundles.

FDIS 2023

I am in Antwerp for the 7th International Conference on Finite Dimensional Integrable Systems in Geometry and Mathematical Physics (FDIS 2023) organized by Sonja Hohloch. I gave a presentation on Rotation 1-Forms and Non-Compact Monodromy based largely on earlier joint work with Andrea Giacobbe and Pavao Mardešić.

SNSA 2023 and SPCSC 2023

I am currently in Zhangye for the 9th Shanghai International Symposium on Nonlinear Sciences and Applications (SNSA 2023) organized at Hexi University, and then I go to Kunming for the 7th Chinese Conference on Statistical Physics and Complex Systems (SPCSC 2023).

Workshop on Finite Dimensional Integrability in Mathematical Physics at Les Diablerets

Between June 11 and 15, I am at the SwissMAP Research Station in Les Diablerets for the workshop Finite Dimensional Integrability in Mathematical Physics.

Visit Shaanxi Normal University

Between June 5 and 8, I visited Prof. Xingang Wang and his group at Shaanxi Normal University in Xi’an, for discussions and I gave a seminar talk to his group about Collective Dynamics of Coupled Oscillators.
