I am a PhD student in Theoretical Physics, working in the group of Gemma De les Coves at the University of Innsbruck. Since 2022 I am a DOC fellow of the Austrian Academy of Sciences.
My research interest is an intersection of physics, mathematics, and computer science. I work on problems related to Computational Complexity Theory applied to physical problems, Categorical Probability Theory, and tensor network decompositions with positivity constraints.
