I am a tenured assistant professor (UD) at the Mathematical Institute of the University of Leiden. My official website is here.
Before this, I was a Postdoc/associate member at the Hausdorff Center for Mathematics and the University of Bonn. Here is my CV.
Research Interest:
Birational geometry, Hyperkähler geometry, generic vanishing theory, Hodge modules and Hodge theory.
I do to not publish papers, reviews, referee reports generated by AI models.
None of these papers had anything to do with AI.
