Dear colleagues, We are happy to announce the forthcoming workshop entitled "Roadmap for EvoDevoMec", Nov. 2nd - 5th, 2026, Université Paris Cité. The link with evolutionary history of an organism is key to understand embryonic development. Much of the focus has been so far on genetic circuitry. However, it has become increasingly clear that physical constraints are an essential aspect at the basis of morphogenetic processes. We have now reached an exciting stage where it becomes possible to integrate mechanical considerations in our view of how development has been shaped during evolution: EvoDevMec. This new approach has recently raised great interest, but biological questions still need to be reformulated with precision. In addition, due to its integrative nature, it poses a scientific and technical challenge: What type of experimental systems could be used? How could we define experimental proof of concepts? How can theoretical biophysical models help integrate various questions and approaches? We aim at discussing these questions in an informal context, i.e. with chalk talks. The workshop is limited to 30 persons, from PhD students to senior scientists from various countries. We will welcome biologists using a breadth of models (from unicellular organisms to animal and plant models), physicists (theoreticians, numericians, experimentalists), and mathematicians.
