--- moi --- ----------- I'm a postdoc at the Laboratoire Jacques-Louis Lions, UPMC, Sorbonnes Universités, Paris, France. I just recently moved to Paris from Sydney, Australia. 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 guitar and rubbish piano. I try to code elegantly. Far too much of my time goes to tinkering with bikes and mobile sound systems.
