Welcome to my homepage! I'm a Courant Instructor in Courant Institute of Mathematical Sciences, New York University.
Research:
My interests in applied math lie at the intersection of differential equations and dynamical systems, probability, and geometry. Example topics include: (1) the analysis and numerics of multiscale systems, and their applications; (2) geometric mechanics and structure-preserving integrators; (3) rare events and sampling for physical and statistical purposes; (4) theory of uncertainty quantification and engineering applications.
