I completed my PhD at Edinburgh University in 2012 under the supervision of Nikolaos Bournaveas. My thesis was on local and global well-posedness of various Dirac models. Subsequently I spent two years as a Chapman Fellow at Imperial College London, and a year visiting Hans Lindblad at Johns Hopkins University.

Current research interests: My research interests lie somewhere in the intersection of partial differential equations (in particular nonlinear dispersive equations), and euclidean harmonic analysis. Recently I have been working on robust forms of bilinear restriction estimates and applications, and asymptotic behaviour of various Dirac models, including the cubic Dirac equation (also known as the Thirring model), and the Dirac-Klein-Gordon equation.

Workshop: Nonlinear Dirac equations and related problems

Sebastian Herr and I organised a workshop focusing on nonlinear Dirac equations and related dispersive problems. The workshop took place on May 28 — 30, 2018, at the University of Bielefeld.
