I am a Postdoctoral University Assistant in the Quantum Information and Quantum Many-Body Physics group at the University of Vienna.

Previously, I was a Ph.D. student in the group of Gemma De les Coves at the University of Innsbruck

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.
