I am interested in G2 and Spin(7) manifolds. More specifically, I am working on problems related to their calibrated submanifolds (they are of dimension 3 or 4). In my current project, I use algebro geometric techniques to understand the minimal compactification of the (complexified) Cayley Grassmannian. I am also interested in Seiberg-Witten theory, low dimensional topology and applications of algebraic geometry to these topics.
