I work in algebraic geometry, sometimes with a view on arithmetic geometry. I am especially interested in the topology and homotopy theory of algebraic varieties and rigid-analytic spaces.
I got my PhD in Mathematics in 2015 from University of California, Berkeley under the guidance of Arthur Ogus. The first three years of my PhD were supported by an International Fulbright Science and Technology Fellowship. I spent the first two years after my PhD (2015-2017) as an EPDI postdoc at the Banach Center at IM PAN in Warsaw and at the IHES in Bures-sur-Yvette.
My thesis K(pi, 1) Spaces in Algebraic Geometry.

We are planning to one PhD student and one postdoc to join our research group. The deadline for applications is May 25 (PhD) and Jun 10 (postdoc).
See project webpage.
A conference organized by Wiesława Nizioł and myself.

Together with Jarek Buczyński, Nathan Ilten, and Masha Vlasenko, we are organizing a topics semester on algebraic and arithmetic geometry titled Varieties: Arithmetic and Transformations. The activity is part of the Simons Semesters program at IMPAN.
More info on the event's website: Varieties: Arithmetic and TransformationsTogether with Adrian Langer and Masha Vlasenko, we are organizing a school on the arithmetic of differential equations in Łukęcin at the Baltic shore close to the German border. The school belongs to the cycle of September Algebraic Geometry Schools organized since 1973. This year's school is part of the Simons semester Varieties: Arithmetic and Transformations at IMPAN.
There will be lecture courses by Kiran Kedlaya and Fernando Rodriguez-Villegas.

One of the main goals of this seminar is to understand what $E_\infty$-algebras are and how one can do commutative algebra with them. We are mostly following Lurie's book Higher Algebra. The seminar is organized by Agnieszka Bodzenta, Bruno Stonek, and myself.
The group meets on Thursdays at 2:15-4pm in room 5050 at MIMUW.
I am one of the organizers of this school, which is part of the semester program Varieties: Arithmetic and Transformations. See more under News.
This is part one of the former preprint "Liftability of the Frobenius morphism and images of toric varieties" [arXiv], split off during the review process.

Note. During the review process, the preprint Geometric arcs and fundamental groups of rigid spaces (arXiv:2105.05184v2, 61 pages) has been split into two papers, this one and Variants of the de Jong fundamental group listed below.
