Vahagn Nersesyan, PhD

Vahagn Nersesyan joined University of Versailles as an Associate Professor in 2009. He holds an HDR in Mathematics from University of Versailles, France and PhD in Mathematics from University Paris 11, France. Vahagn's research interests are in the intersection of the analysis of partial differential equations (PDEs) and probability theory. He is particularly interested in problems of controllability and stabilization of PDEs and in problems of ergodicity, large deviations, and entropic fluctuations of randomly forced PDEs.
