Short Bio

I am Joshua Moerman, a computer scientist. Currently, I am assistant professor at the Open University of the Netherlands.

Before, I did a PostDoc at the RWTH Aachen in the MOVES group, where I was working on probabilistic programs as a member of the FRAPPANT project.

I received my PhD at the Radboud University in Nijmegen at the Software Science department. Under supervision of Frits Vaandrager, Bas Terwijn, and Alexandra Silva I worked on nominal automata and black box testing in the context of active automata learning.

My research interests include formal verification, PAC learning, coalgebraic methods, functional programming, black-box testing theory, and category theory.
