Dipl.-Inf. Lukas Gerlach

Research Associate Knowledge-Based Systems

Hi!

I'm Lukas and I'm a Research Associate / PhD student in the Knowledge-Based Systems group. I mainly research existential rules, the chase algorithm and related topics. During my studies, I specialized in database theory, logics and complexity theory. Also, I have a passion for Lean.
