I am a postdoctoral Humboldt Research Fellow based at the Institute of Algebraic Geometry within Leibniz Universität Hannover. Geometry fascinates me, with algebraic methods my preferred means of exploration. In particular, I think a lot about rational curves, rationality problems, and geometry in positive characteristic.

During the autumn of 2024, I am:

- organizing a working seminar with Stefan Schreieder around rational curves in algebraic varieties; see here for more details.
- thinking about unirationality of a large class of high degree hypersurfaces in positive characteristic. These are related to the \(q\)-bic hypersurfaces that feature in this and this paper; also take a look at this talk I gave a while ago!
- thinking about derived categories of quadric bundles with Noah Olander!
- thinking about Prym varieties and cubic fourfolds in characteristic \(2\) with Gebhard Martin and Dominique Mattei.
