Dr. Stephan Mennicke

Research Associate Knowledge-Based Systems

I'm a postdoctoral researcher at the Knowledge-based Systems group led by Prof. Dr. Markus Krötzsch. I'm interested in knowledge representation, graph databases and their query languages, as well as process modeling and formal methods.

I got my master's degree from TU Braunschweig. In March 2020, I successfully defended my PhD thesis on Non-Standard Semantics of Graph Query Languages. I've worked on Theory of Programming Languages (together with Prof. Ursula Goltz and Prof. Uwe Nestmann) and "Semantics of Graph Pattern Queries" (together with Prof. Wolf-Tilo Balke). Additionally, I contributed some formal methods for software product lines (SPLs).
