Jason van Zelm

Hello and Welcome to my website!

I am a young Postdoc working in Algebraic Geometry currently employed at Humboldt Universität zu Berlin. I did my PhD at the University of Liverpool supervision of Nicola Pagani.

Research Interests: I am interested in moduli spaces of curves, intersection theory, enumerative geometry and Gromov-Witten theory. 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.
