Dr Anastasia Papavasiliou got her PhD from Princeton University in 2002, working on stability questions for stochastic filtering and particle filters. Before coming to Warwick, she taught at Columbia University for a couple of years and spent another year in Princeton, working on efficient simulation methods for multiscale stochastic systems. Stochastic filtering, multiscale systems and, stochastic simulations are still some of her research interests, while recently she has working on applying ideas coming from the theory of rough paths to statistics.
Anastasia joined the Department of Statistics as a lecturer in 2005.
