Thierry Goudon (born January 1969 in Aix-en-Provence, France) is a French mathematician. He works in applied mathematics, with interest in the study of Partial Differential Equations motivated from physics. He has made contributions on kinetic theory, which corresponds to a description of matter in terms of statistical physics. The Boltzmann equation for gas dynamics is a typical example of this activity. The kinetic framework also arises in many other fields: neutron transport, radiative transfer, and biology. He is interested in asymptotic analysis, including the study of hydrodynamic regimes and homogenization theory, establishing relationships between microscopic and macroscopic descriptions. He also works on fluid mechanics, both as regards the analysis of the equations and also the d
