Sjoerd Beentjes

Welcome to my homepage! I am a mathematican based at the Hausdorff Center for Mathematics in Bonn, working with Georg Oberdieck. I am part of the Complex Geometry group led by Daniel Huybrechts.

During the academic year 2019-2020, I am on leave from the University of Edinburgh where I work as a postdoctoral fellow with Ben Davison. Before that, I completed my PhD in 2018 under the supervision of Arend Bayer, also at the University of Edinburgh.

Research Interests:

Algebraic Geometry, in particular enumerative geometry, stability conditions and derived categories, Calabi-Yau threefolds, (non-commutative) Donaldson-Thomas theory, and motivic and cohomological Hall algebras.

Applications of pure mathematics in biomedicine.

Papers and preprints:

  1. Virtual counts on Quot schemes and the higher rank local DT/PT correspondence, 2018
    (with Andrea T. Ricolfi) Math. Res. Lett, to appear.
  2. A proof of the Donaldson-Thomas crepant resolution conjecture, 2018
    (with John Calabrese and Jørgen Vold Rennemo) Submitted.

I am interested in applications of pure mathematics to questions arising in biomedicine. With my collaborators, we have developed a toolkit to estimate the persistence of DNA lesions segregating unrepaired into daughter cells in a model of chemically induced cancer.

Other fields:

  1. Pervasive lesion segregation shapes cancer genome evolution
