About me

I am a research and teaching assistant at TU Berlin. As a Phase II student, I am part of the Berlin Mathematical School and the research group of "Algebraic and Geometric Methods in Data Analysis" led by Carlos Améndola. I received my M.Sc. in Mathematics at OvGU Magdeburg under the supervision of Thomas Kahle and Carsten Conradi.

Research

My main research interest is algebraic statistics, in particular likelihood geometry of toric models. More broadly, I am also interested in developments regarding discrete and applied algebraic geometry.

Peer-reviewed articles and preprints:

• Euler Stratifications of Second Hypersimplices via Delta-matroids
  Single-author paper (2026).
• Identifiability in Graphical Discrete Lyapunov Models
  with C. O. Recke, S. Lumpp, N. Kushnerchuk, J. Li, J. I. Coons, and E. Robeva (2026).
• The Maximum Likelihood Degree of Toric Models is Monotonic
