I am a postdoctoral researcher in the Center for Vision, Cognition, Learning, and Autonomy (VCLA) at UCLA, under the supervision of Prof. Song-Chun Zhu. I obtained my Ph.D degree at Centre de Mathématiques et de Leurs Applications (CMLA), Ecole Normale Supérieure de Cachan, France under the supervision of Prof. Jean-Michel Morel. Prior to that, I received the diplôme d'ingénieur from Ecole Polytechnique, Palaiseau, France and B.E. from Fudan University, Shanghai, China respectively. My current research interest lies in statistical modeling and machine learning, with applications to computer vision.
