Leopold Karl

I am a mathematician, currently pursuing my PhD in the Algebra Group at TU Wien with Michael Pinsker, employed on the ERC Synergy Grant POCOCOP. My research interests lie in (universal) algebra, topology, model theory, and mathematical logic, and their applications to Constraint Satisfaction Problems (CSPs).
