I am an applied mathematical analyst; my current interests are in Inverse Problems, Applied and Computational Harmonic Analysis, and Statistical Signal Processing and Analysis. I am particularly interested in inverse problems in imaging, compressed sensing, as well as applications of higher-dimensional probability to statistical signal estimation. I have previously worked in Pure Maths, mainly Analysis, and specifically on (deterministic and stochastic) Partial Differential Equations, Harmonic Analysis, and Geometric Analysis: most of my work has been on nonlinear dispersive and parabolic differential equations, but I have also studied variational elliptic PDEs with ideas from Nonlinear Functional Analysis. Before that, I did some work in Mathematical Control Theory.
