Welcome to my home page!

This semester I'm a postdoc at the Osnabrück University,

in the research group of Oliver
Röndigs and Markus Spitzweck.

The focus of our research group is motivic homotopy theory,

which applies powerful methods of algebraic topology

to shed light on mysteries of algebraic geometry.

I did my PhD under supervision of Marc Levine

at the
Duisburg-Essen University.

And here is a story how my PhD program started: Jail-dreaming

"The more I learned, the more conscious did I become of the fact that I was ridiculous. So that for me my years of hard work at the university seem in the end to have existed for the sole purpose of demonstrating and proving to me, the more deeply engrossed I became in my studies, that I was an utterly absurd person."

- On 13th March I turned 25 and graduated! Here is my thesis.

- I organized a seminar in Osnabrück on "Norms in motivic homotopy theory" (after Tom Bachmann and Marc Hoyois).

- On 19th June I will give a talk in the Algebra and Topology Seminar of Strasbourg University.

Title: The space of algebraic cobordism

Abstract: Classically, the universal oriented cohomology theory is represented by the complex cobordism spectrum MU, which has a description
in terms of cobordism spaces of compact smooth manifolds with an extra structure. In motivic settings, there is an analogous spectrum MGL, constructed by Voevodsky. In this talk we will discuss a
model for the infinite loop space of MGL as an algebro-geometric incarnation of the cobordism space. Time permitting, we will discuss some applications, in particular a recognition principle
for

MGL-modules. This is joint work with Elden Elmanto, Marc Hoyois, Adeel Khan and Vladimir Sosnilo.

- On 6th May I gave a talk in the conference "Algebro-Geometric and Homotopical Methods" at the Mittag-Leffler Institute.

Title: Encoding transfers in motivic homotopy theory

Abstract: Voevodsky’s approach to constructing the (derived) category of motives starts with introducing so called presheaves with
transfers. Later Calmès and Fasel added extra data of quadratic forms to this construction, by considering presheaves with Milnor-Witt transfers. We will show that these transfers are examples of
a more general construction of E-transfers, defined for any motivic ring spectrum E. We will also discuss relation of E-transfers with framed transfers, and some consequences for understanding
the category of E-modules. This is joint work with Elden Elmanto, Marc Hoyois, Adeel Khan and Vladimir Sosnilo.

- During 23-29 June I will take part in the "Algebraic K-theory"
workshop in Oberwolfach.

- 9-12 July I will spend in the Institute of Math in Warsaw, visiting Joachim Jelisiejew.

- During July 18-31 Elden, Marc, Adeel and I will be staying at IAS as Summer collaborators.

- ICM 2022 will happen in St. Petersburg, with visa-free entry for all participants!
