Research
My research interests include global surface geometry, integrable systems and moduli space of
flat connections. In particular, I am interested in the construction of compact minimal, CMC and
Willmore surfaces in the 3-sphere. I also work on Higgs bundles Hitchin equations, and the
construction of related hyper-kaehler metrics. Recently, I have been investigating several
problems concerning the monodromy representation of holomorphic systems.
Three views of a constant mean curvature surface in the 3-sphere. Images by Nick Schmitt based on the joint paper 'Deformations of symmetric CMC surfaces in the 3-sphere'.
