Postdoctoral Fellow in Mathematics, NYU Shanghai
Grégoire Véchambre is a Postdoctoral Research Fellow in Mathematics at NYU Shanghai. He holds a Ph.D. from Orléans University, received in November 2016, and prepared under the supervision of Dr. Pierre Andreoletti. Before his PhD, he studied mathematics in the Britanian branch of ENS Cachan (that school became ENS Rennes in 2014).
Grégoire Véchambre's work lies in probability theory. His research interest are mainly in processed random environments, Lévy processes, and exponential functionals of Lévy processes.
