On this page you can find brief descriptions of my work, along with links to papers and various notes that I have typed up.

For the mathematicians

My work is focussed on geometric variational problems, formulated in the languages of geometric measure theory and PDE. In particular I am interested in those problems arising from the study of the area functional of submanifolds of Euclidean space or, more generally, a Riemannian manifold. I have worked on problems relating to mean curvature flow (which is like the gradient descent for area), where I am mostly interested in the process of singularity formation and the existence and regularity of weak solutions. I also am interested in the regularity of stationary varifolds (these are measure theoretic notions of minimal submanifolds, and so are critical for area), and in particular have been recently trying to understand boundary behaviour, and regularity up to the boundary.

For the civilians

I work in an area of mathematics called geometric analysis. Broadly speaking, what this means is that I work on problems in geometry (the study of space and shapes) using techniques and ideas from analysis (this is a rather large area of mathematics that is hard to define well, but relates mostly to calculus and the ideas that arose from its development). More specifically it turns out that many problems in geometry are described by differential equations, and often one hopes that by better understanding the behaviour of the equation and its solutions, one can gain insight into the original geometric problem. This can also work the other way; often the equations that arise from these geometric problems are somehow 'typical' examples of a wider class of equations containing them. One hopes that perhaps insights coming from the geometric picture, could lead to development of techniques that will generalise to the wider class of equations where perhaps there is no obvious associated geometric picture or intuition.
