Algebraic Geometry.
Specifically, I am currently working on problems related to the arithmetic and topology of
Shimura varieties
arising from K3 categories. These categories include (twisted)
K3 surfaces,
their
derived categories,
and the Kuznetsov component in the derived category of a Fano fourfold of K3 type.
Papers
In the list below, my papers on finite (algebraic) geometry are grouped together, while my remaining papers are grouped based on the examples they deal with. This isn't really a good way to organize them, as you may find, e.g., that my papers concerning Cremona transformations are spread throughout those groups.
My papers listed in a reverse chronological order can be found in my CV and arXiv. Before being published on journals, papers on this website will be updated more frequently than those on the arXiv.
