I am a PhD student under the supervision of Wolfgang Dvořák and Stefan Woltran, currently working on the "REVEAL"-project ("Revealing and Utilizing the Hidden Structure for Solving Hard Problems in AI") and the "HYPAR"-project ("Hybrid Parameterized Problem Solving in Practice").
I am particularly interested in
argumentation, computational complexity, structure in AI problems, explanations, and non-monotonic reasoning in general.

Community Activity
I was a program committee member at AAAI 2023 and AAAI 2024 and sub-reviewer for several conferences and workshops, e.g., CLAR, COMMA, SAFA, ...Moreover, I review for Argument & Computation.
