## Interests

I am interested in $G_2$ and Spin(7) manifolds. More specifically, I am working on problems related to complexification of $G_2$ and Spin(7) manifolds and interactions of these geometries with other geometric structures (e.g. contact and symplectic structures). I am also interested in Seiberg-Witten theory, low dimensional topology and applications of algebraic geometry and algebraic topology to problems in differential geometry.
