The JTMS2026 "Journées Théorie, Modélisation et Simulation 2026" will take place at Sorbonne University, on November 3rd and 4th 2026. The main aim of this conference is to gather researchers from our physico-chemical modeling community. These days are an opportunity to get to know each other better, to favor synergies and collaborations. Moreover, it is a good moment for young researchers from our laboratories to get to know the scientific community around them and identify opportunities to share knowledge and know-how.

The JTMS2026 are organized by the subdivision Modélisation et Simulation (ModSim) of the Division de Chimie Physique (common to the Société Chimique de France and the Société Française de Physique).

This year, we are delighted to host for the plenary talks:

• Rocio SEMINO (PHENIX, Sorbonne U)
• Federica MASCHIETTO (LBT, CNRS/UPCité)
• Grégoire DAVID(ISC Rennes)
• Flavio SIRO BRIGIANO (LCT Paris)

ModSim can provide financial support for the participation of young researchers in this event. To do so, please send an email to the organizers when you register.

Looking forward to seeing you there!

The organizing committee.
