Robin Kaarsgaard

Who?

I am (tenure-track) assistant professor in the Section for Artificial Intelligence, Cybersecurity, and Programming Languages at the Department of Mathematics and Computer Science at University of Southern Denmark. I am also associated with the Centre for Quantum Mathematics.

My research focuses on quantum programming languages and their semantics, and more broadly on the applications of category theory to computer science.
