Kelvin Shuangjian Zhang
I am a Postdoctoral Fellow at CREST - ENSAE ParisTech, working with Professor Marco Cuturi and Professor Gabriel Peyré.
I received my Ph.D. degree from Department of Mathematics, University of Toronto in 2018, under supervision of Professor Robert J. McCann. During summer 2018, I visited Professor Guillaume Carlier at MOKAPLAN, INRIA.
