A CNRS France-Japan-Korea-Taiwan research group 


ReaDiNet (Reaction-Diffusion Network) is an International Research Network (IRN) of CNRS composed of french, japanese, korean and taiwanese researchers in the fields of mathematics and its applications in biology, ecology, medicine and chemistry. This International Research Network has started in 2020 and is a sequel of the LIA ReaDiLab (2007 to 2015) and the GDRI ReaDiNet (2015 to 2019). Throughout its history, this project has been continuously expanding both geographically and thematically.

Our scientific goal is the understanding of ecological and biological phenomena through the mathematical analysis of models from the life sciences. Indeed, biology gives rise to a wide range of complex phenomena. Mathematics provides a deep insight on how this complexity can emerge even from relatively simple systems, and conversely the life sciences have been a source for many new and challenging mathematical problems.

Our research bears on both the modelling and the mathematical analysis of various issues in the life sciences. Let us mention the following broad topics:

  • self-organisation, pattern formation and collective behaviours;
  • spatial dynamics and invasion phenomena;
  • modelling optimisation and applications to biophysics and medicine;
  • structured population dynamics and evolutionary biology…

These include more specific topics, both in terms of applications (ecology, medicine, neuroscience, epidemiology…) and mathematical tools (reaction-diffusion systems, stochastic differential equations, mean field limits and multiscale approaches…). We wish to bring together mathematical communities from the fields of partial differential equations and probability theory and also to promote interdisciplinary collaborations between mathematics and the applied sciences.

Forthcoming events:


      • January 3rd to January 6th, 2023: ReaDiNet "International conference on parabolic and stochastic models in population dynamics", at University Paris-Saclay, Orsay (France). More information and registration here.


Notice on traveling:

(last update Nov 2nd) Many travel restrictions have been lifted, and most of the remaining ones are expected to be relaxed in the next few weeks. For these reasons and unless there is a major change in our countries' policies, we will no longer update this section. We encourage everyone to check on embassies' websites for more reliable and updated information (some links are provided below).

  • to France: entry restrictions have been lifted. However, be also careful for restrictions that you may face on your travel back home.
  • to Japan: from October 11th, borders will be fully open to travelers as visa exemptions will restart and entry caps will be removed. Proof of vaccination or a negative test before boarding may still be necessary.
  • to South Korea: visa are not necessary but one must now apply online for an electronic authorization. A test may be still necessary after landing. Provided it is negative, there is no quarantine regardless of vaccination status.
  • to Taiwan: visa requirement has finally been lifted. Upon arrival, travelers must undergo a 7-days "self initiated epidemic prevention". During this period, one must auto-test regularly and avoid social events, but can attend work meetings including conferences.
