My main research interests are in nonlinear PDEs. The methods I use are derived from measure theory, PDEs, geometric analysis, and calculus of variations. from Analysis (mainly partial differential equations and the calculus of variations) to obtain global differential topological results.

However, one needs to use hardcore analytic tools to make rigorous the above formal reasoning. In particular, a central problem is that the minimisers are sought in a class of at most once di erentiable maps, which the PDE is of second order and one has to devise a way to make sense of the PDE Elliptic Partial Dierential Equations in Geometric Analysis and the Calculus of Variations Aleksis Koski A thesis presented for the degree of Doctor of Philosophy them solving certain PDE s, and studying these equations lets us understand these functions better.
