My research interests relate to Topological Solitons and their links to geometry, Differential Geometry and Gauge Theory. In particular my PhD work focused on studying a geometric interpretation of integrable vortex equations. I have continued working on this as well as studying the relationship between vortices and BPS monopoles. More recently I have worked on solvable models of magnetic skyrmions, as well as domain walls in one dimensional chiral magnets.
