I am a Juniorprofessor for Algebraic Geometry at the Faculty of Mathematics at Ruhr-University Bochum. My research focus lies in birational geometry. Some of the objects and questions that I like are: groups of automorphisms of complex algebraic varieties, various cones (nef, movable, big, effective) providing notions of positivity for divisors on complex projective varieties, the Morrison-Kawamata-Totaro cone conjecture, techniques of the Minimal Model Program, positivity properties of the (co)tangent sheaves and their Chern classes, families of rational curves deforming in a (most often Fano) variety.

Before coming to Bochum, I obtained my Ph.D. in February 2023 at Université Côte d'Azur under the supervision of Andreas Höring.

From May 2023 to September 2024, I worked as a postdoctoral fellow in the group led by Gavril Farkas at Humboldt-Universität zu Berlin.

I am the Mercator fellow of the SFB-TRR 195 Symbolic Tools in Mathematics and their Applications. Congratulations to the PIs for securing this third extension!

I'm an associated foreign member of the ANR project Groups in Algebraic Geometry (GAG).

What's up here in Bochum

• * New * Our guest seminar (Oberseminar) on Algebraic and Complex Geometry resumes for the Winter Term 25/26. It takes place on Thursdays from 14 to 16. The speakers line-up is available here. Past talks are archived on my events page
• I'll be teaching Algebraic Geometry I in the Winter Term 25/26. Here is the Moodle page to sign up. References and teaching material will be on my teaching page.

Where I'll be next

• September 22nd - 26th: SFB-TRR 195 annual meeting in Tübingen.
• October 27th - 30th: Boundedness and Moduli Problems‏ in Birational Geometry and Foliation Theory in Pisa.
• November 20th: Seminar Algebraische Geometrie in Bonn.
• December 7th-12th: Algebraic Foliations: Analytic and Birational Viewpoint in Oberwolfach.

Office IB3/89, Postfach 45
Note that the building is named IB, and that my office is on the floor numbered 3 (not to be confused with 03).

A map is displayed at the entrance of the campus, you can also find one here. A quick summary: Coming with the U35, stop at Ruhr-Universität. Exiting the station, go to your right towards the campus. After 100 meters, you should see the library. Circle it to the left. Looking farther to the left and down, you should see three large parallel, modern-looking buildings: IB is the second-closest to where you stand.
