Rudolf Freund is a retired Professor at the Vienna University of Technology (TU Wien), affiliated with the Department of Theory and Logic (E192-05) under the Faculty of Informatics. His research focuses on formal languages, membrane computing (P systems), theoretical computer science, and bio-inspired computational models. He has contributed extensively to areas such as infinite words, graph grammars, molecular computing, and neural networks. Freund has held roles including editor for conference proceedings (e.g., NCMA 2019) and has taught courses like Formal Language Theory and Introduction to Clinics. His work often bridges theoretical foundations with practical applications in computing systems, emphasizing formal verification and computational completeness. His research has been published in journals like Natural Computing and Theoretical Computer Science , exploring topics such as derivation modes in P systems, reactive membranes, and computational models for Boolean networks. Despite retirement, he remains active in academic activities, including organizing workshops and contributing to conferences on unconventional computing. Freund's expertise spans membrane computing variants, automata theory, and regulated rewriting systems, with a focus on advancing computational paradigms inspired by biological processes.
