Pascal joined the Intelligent Autonomous Systems Group in May 2019 as a PhD student working on the ROBOLEAP project. He defended his PhD thesis in November 2023. In general, his research interests revolve around various aspects of reinforcement learning that, in his opinion, will be crucial to tackling challenging reinforcement learning problems - two of them being knowledge transfer and learning via curricula. He is convinced that learning systems need to be able to reuse previously acquired knowledge to speed up and bootstrap learning in new situations in order to tackle the most challenging tasks.

Before starting his PhD, Pascal completed his Bachelor's degree in Computer Science and Master's degree in Autonomous Systems at the Technische Universitaet Darmstadt. He wrote his Master's thesis on "Generalization and Transferability in Reinforcement Learning" supervised by Hany Abdulsamad, Boris Belousov and Jan Peters, where he investigated concepts from the domain of numerical continuation, parameteric programming and concurrent systems theory for the task of knowledge transfer and finally developed a method for autonomous curriculum generation for reinforcement learning problems.
