About me
I am currently a postdoctoral researcher in the research group of Thomas Rot at the Vrije Universiteit Amsterdam. Before that I was a postdoc with Mélanie Bertelson, and a PhD under the supervision of Marius Crainic and Alvaro del Pino.
Among other things I am interested in contact structures, symplectic foliations and h-principle techniques.
