The goals of this conference are to bring together some of the leading experts in stochastic analysis and PDEs, dealing in particular with the study of the asymptotic properties of stochastic systems with multiple scales, to present their recent research and exchange ideas, and to provide an opportunity for graduate students and young researchers to be exposed to these fields. This conference will be also an occasion to celebrate Mark Freidlin and his many fundamental contributions to the study of various aspects of the theory of random perturbations of dynamical systems.
