Bio - Dynamics - Days (BDD) 2023 - 8th Edition   

Mathematics with Applications to Life Science:

Modeling, Nonlinear Dynamical Systems, ODE, PDE, DDE, Bifurcations, Chaos, Turbulence, Statistics, Stochastics, Data Science, Complex Systems and Interacting Networks. With applications to Neuroscience, Epidemics, Population Dynamics, Ecosystems ....


The Lab of Mathematics of Le Havre university (LMAH), supported by several structures (Le Havre Normandie University, Federation Normandie Mathematics FR-CNRS-3335 FNM , AMIES (PEPS), CNRS (IEA), the ISCN , the Normandie region RN, the French Speaking Society for Theoretical Biology (SFBT) and by a network of researchers from Normandie), develops as a unifying theme: Complex Systems, in particular Dynamical Systems, Networks and Applications to life science (Brain dynamics, Epidemiology, Ecosystems...). It organizes the Bio Dynamics Days (BDD) from several years. In June, BDD2023 will be organized in hybrid mode between France and the US with the support from diffferent schools. The speakers are:
