Maître de conférences Hors Classe · UMPA, École Normale Supérieure de Lyon

Dynamical systems · mathematical biology · artificial intelligence

I work on dynamical systems and celestial mechanics — including the classical three-body problem — and, over roughly a decade, on mathematical models of tumour–immune dynamics, cancer immunotherapy and antiviral immunity. I also work on machine learning methods for biological sequence data, and coordinated PEPS SIGMAPAD, a CNRS programme on artificial intelligence and machine learning.

Expert consulting

Mathematical modelling of tumour–immune dynamics, cancer immunotherapy and antiviral immune response; delay differential equation models; neural network methods for biological sequence analysis. Also dynamical systems, celestial mechanics and integrability.

Since 2024, I am AMIES correspondent for UMPA — the French national agency for mathematics-industry interaction (Agence pour les Mathématiques en Interaction avec l'Entreprise et la Société).

Available for expert consultations, independent model review and short advisory engagements. Enquiries: alexei.tsygvintsev@ens-lyon.fr
