About me

I am Joshua Moerman, a computer scientist. Currently, I am a post doctoral researcher at the RWTH Aachen in the MOVES group. I am working on probabilistic programs as a member of the FRAPPANT project.

Formerly, I was a PhD student 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 also include formal verification, PAC learning, coalgebraic methods, functional programming, black-box testing theory, and category theory.
