Professor Anastasia Papavasiliou

I got my PhD from Princeton University in 2002, working under the supervision of Professor Rene Carmona on stability questions for stochastic filtering and particle filters. In my final year as a PhD student, I had the opportunity to visit Professor Terry Lyons in Oxford, where I was introduced to the theory of rough paths. While working as a postdoctoral research associate for Professor Yannis Kevrekidis, I got interested in problems related to statistical inference and simulation for mutlscale systems. I joined the Department of Statistics as a lecturer in 2005 and my research since combines all these three themes.

Recently, I have been introduced by my sister, Nina Papavasiliou, Professor of Immunology at DKFZ, HeidelbergLink opens in a new window, to the world of RNA modifications, which is an emerging field in immunology, rich in statistical challenges.
