Pseudogroups and geometric structures
(with Francesco Cattafi, Marius Crainic, and María Amelia Salazar)
This is a book describing a modern approach to the theory of Lie pseudogroups and geometric structure on manifolds that builds upon the theory of Lie groupoids, principal groupoid actions, and multiplicative structures. The main achievements include a clarification of the foundations of Élie Cartan’s work on the subject and a framework capable of dealing with non transitive pseudogroups.
Horizontal Morse Theory
(with Fabio Gironella, Álvaro del Pino Gómez, and Lauran Toussaint)
This paper develops a version of Morse theory compatible with a codimension one distribution on a manifold.

Local reading seminar co-organized with Francesco Cattafi at Universiteit Utrecht, and based on the classical sources by Robert Bryant.
Equivariant cohomology
Published:
Local reading seminar co-organized with Maarten Mol and Sergej Monavari at Universiteit Utrecht. We started from the classical paper by Atiyah and Bott on the subject, and moved to various related topics.
