Alexander Beiser

Alexander Beiser is a Researcher at TU Wien's Department of Databases and Artificial Intelligence, part of the Faculty of Informatics. His work focuses on neurosymbolic reasoning, logic programming systems like Answer Set Programming (ASP), and hybrid grounding techniques to optimize computational workflows. He teaches the 2025S Algorithms and Data Structures course (186.866) as a VU lecture. His research bridges formal methods with practical applications in AI, emphasizing user interaction frameworks (e.g., clinguin) and improving efficiency in logic-based systems.

Key areas include advancing neurosymbolic integration with LLMs, optimizing ASP-driven systems through hybrid grounding, and developing tools for interactive logic programming. Recent contributions address bottlenecks in grounding processes via splitting and rewriting strategies, aiming to enhance scalability in complex reasoning tasks.
