Jason van Zelm

I am a young Postdoc at Humboldt Universität zu Berlin. I did my PhD at the University of Liverpool supervision of Nicola Pagani.

Research Interests: Algebraic Geometry: moduli spaces of curves, intersection theory and enumerative geometry. In particular I am currently studying cycles on the moduli space of curves arising from spaces of admissible covers.

A paper version of my CV can be found here.
