I am a PhD student at TU Berlin, working under the joint supervision of Carlos Améndola and Ben Hollering as part of the “Combinatorial Methods for Learning Max-Linear Bayesian Networks” project of the “Combinatorial Synergies” DFG priority programme (SPP 2458).
I obtained my master’s degree in mathematics in 2024, also at TU Berlin. I wrote my thesis on Gröbner walk algorithms (pdf).
My main research interests are in the areas of discrete geometry, combinatorics, and computational algebra. More recent interests include algebraic statistics and the development of mathematical software.
A PC Algorithm for Max-Linear Bayesian Networks (with C.Améndola, B.Hollering)
Polyhedral Aspects of Maxoids (with T.Boege, B.Hollering, K.Ferry)
The GröbnerWalk.jl package for OSCAR (with K.Ferry)
This github repo contains code for separation criteria and causal discovery in Max-Linear Bayesian Networks.
Kamillo Ferry and I are developing the GroebnerWalk julia package, which implements several versions of the Gröbner walk in OSCAR.
