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!

What's up here in Bochum

• It's the semester break. Our guest seminar on Algebraic and Complex Geometry is taking a break too.
• * New * We'll have a workshop on D-modules from March 5th to March 7th with mini-courses by Yagna Dutta, Andreas Hohl, and Thomas Krämer. More information available here.
• I'll be teaching Commutative Algebra next term. More information on that soon.
• * New * There is a 3-year PhD position currently open in my group with an expected starting date around September 2025. More information on it here, and the legally binding job post in German there. Feel free to email me if you are interested, want more information on the position, or desire to apply. The application deadline is on April 6th.

Where I'll be next

• February 18th: Seminari di Algebra, Geometria Algebrica e Applicazioni in Torino.
• Feburary 24th - 26th: Kick-off Workshop of the ANR GAG in Grenoble. Looking forward to learn about L^2 Betti numbers!
• March 13th: Séminaire Géométrie algébrique in Lille.
• March 14th: Séminaire Géométrie in Bordeaux.
• April 21st - 25th: Conference Families of Kähler spaces in Luminy.

Office IB3/89
Note that the building is named IB, and that my office is on the floor numbered 3 (going up from street level).

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, go around it from the left. Looking farther to the left and down, you should see three large, modern-looking buildings: IB is the second-closest to where you stand.
