Zhenjie Ren is currently an assistant professor at CEREMADE. After the undergraduate and master study on pure and applied Mathematics in Fudan University (Shanghai, China), he moved to France and got a PhD in Financial Mathematics. His research is mainly concerned with the problems arising from optimization and control, and motivated by the applications in finance, economics and machine learning. More generally, he is interested in various topics across probability, partial differential equation, game theory etc.
