I am a differential topologist that studies geometric structures. The questions I consider are often of the form: “What is the homotopy type of the space of all geometric structures of class X on a given manifold M?

This is a rather broad question, since it can be posed in any geometric setting you like. I mostly spend my time thinking about:

  • h-Principle (i.e. about developing techniques, with the goal of answering the question above, that are general and not geometry-specific). Some keywords: wrinkling, convex integration, removal of singularities.
  • Tangent distributions (i.e. subbundles of the tangent bundle), particularly under the assumption that they are bracket-generating (and often maximally non-integrable). Some keywords: horizontal submanifolds, Engel structures, (2,3,5)-distributions, (4,6)-distributions, Cartan distribution.
  • Poisson Geometry and Foliation Theory. Some keywords: symplectic foliation, contact foliation, Lie algebroid, transverse geometry.

Furthermore, I am very interested in Contact and Symplectic Topology (as the main inspiration behind the things I do), Sub-Riemannian Geometry (as the field that studies distributions from a geometric perspective), and Homotopy Theory (concretely, its relation to h-principle).
