About me

I obtained my Ph.D. degree in mathematics from Utrecht University under supervision of Gil Cavalcanti on August 29, 2017. I am a member of the Geometric Structures group at Utrecht University, led by Marius Crainic. I obtained my master's degree in mathematics from Utrecht University, and hold bachelor's degrees in applied physics and applied mathematics from Eindhoven University of Technology.

Starting from September 2017, I will be a postdoctoral researcher in the geometry group of the Université libre de Bruxelles, working with Joel Fine.

Research interests

My research interests are in the fields of Poisson geometry and generalized complex geometry. Moreover, I am interested in surrounding areas such as symplectic geometry, gauge theory, Dirac geometry, index theory, and low-dimensional topology. My main interest lies in using Lie algebroids to apply and extend symplectic techniques to Poisson and generalized complex structures. I am also interested in extending techniques from Seiberg-Witten theory to this setting.
