DESCRIPTION:Kinetic equations play a major role in modeling large systems 
 of interacting parti cles/agents with a proven effectiveness in describing
  real world phenomena ranging from plasma physics to biological dynamics. 
 Their formulation has often to face with physical forces deduced through e
 xperimental data of which we have at most statistical information. To that
  aim\, we consider in this talk the presence of random inputs in the form 
 of uncertain parameters as a structural feature of the kinetic modeling. M
 ore in detail\, we deal with uncertainty quantification for the Vlasov-Fok
 ker-Planck equations and we discuss a numerical method employing a micro-m
 acro approach based on stochastic Galerkin methods which preserves the lar
 ge time equilibrium distribution of the system. The theoretical properties
  of the scheme as well as numerical experiments will be discussed during t
 he talk.
