--- moi --- ----------- I'm a postdoc at the Laboratoire Jacques-Louis Lions, UPMC, Sorbonnes Universités, Paris, France. I'm interested in approximation, high dimensional problems, fractional & stochastic partial differential equations, stochastic processes, numerical analysis, and machine learning. I completed my Ph.D in 2014 with Ian Sloan and Frances Kuo, at UNSW, Sydney, Australia. I play some banjo and a bit of piano. I try to code elegantly. I love riding and tinkering with bikes.
