I am a PhD student under supervision of Ben Moonen. My main interest lies in algebraic geometry and algebraic number theory. I am funded by NWO project 613.001.207 (*Arithmetic and motivic aspects of the Kuga-Satake construction*).

Current research topics include: Hodge theory, reductive groups and their representations, `p`-adic Hodge theory, Galois representations, motives.

I wrote my master's thesis, titled Algebraic cycles, Chow motives, and L-functions, in the spring of 2013 under the supervision of Robin de Jong.

I wrote my bachelor's thesis, titled Tannaka Duality for Finite Groups, in the spring of 2011 under the supervision of Lenny Taelman.
