Our research ranges from the general (i.e. the development of abstract frameworks to tackle the study of geometric structures) to the specific (the study of concrete geometries). In doing so, we borrow tools from Algebra, Geometric Analysis, and Homotopy Theory. Some of our research interests include:

- Foliation Theory
- Generalised Geometry
- Geometry of PDEs
- h-Principle
- Index Theory
- Lie Theory, including Lie algebroids and groupoids
- Non-linear elliptic PDEs and their applications in Differential Topology
- Poisson Geometry
- Symplectic Geometry and Topology, Contact Topology
- Subriemannian Geometry

Our members are part of the Dutch cluster on Geometry and Quantum Theory (GQT).
