Stefan Ellmauthaler

With over 12 years of academic expertise in AI, knowledge representation, and computational logic, I am passionate about bringing cutting-edge Computational Intelligence (CI) solutions to real-world challenges as I transition into new frontiers.

I am transitioning into the industry, bringing over a decade of research and experience in higher education, computational complexity theory, mathematical logic, and knowledge representation and reasoning. I’m passionate about leveraging my expertise with AI and I am currently in the process of founding a company, helping others identify their specific needs for various techniques, including AI, and choose the right methods.

At Leipzig University (Intelligent Systems Group), I focused on Artificial Intelligence and Knowledge Representation, working on distributed reasoning and exchange of information.

At the Center of Scalable Data Analytics and Artificial Intelligence (ScaDS.AI), the International Center for Computational Logic (ICCL), and the Knowledge-Based Systems Group, which are all part of TU Dresden, I focused on existential rules, argumentation theory, and ontology-based data access. There I have also been working at the industry-oriented ITEA project InnoSale (Innovating Sales and Planning of Complex Industrial Products Exploiting Artificial Intelligence).

I led the development of a software bundle to solve argumentation problems using Binary Decision Diagrams and No-Good Learning methods. I’ve worked on the first steps for the in-memory datalog reasoning engine Nemo too.

I’m experienced in managing IT Projects with multiple partners from academia and industry and have a long history of applying symbolic AI and enabling others to understand and utilize such approaches.

Academic education

I earned my B.Sc. in “Medicine and Computer Science” in 2009 and my diploma in “Computational Intelligence” in 2012, both from the Vienna University of Technology. In 2018, I defended my doctoral thesis “Multi-Context Reasoning in Continuous Data-Flow Environments” under the supervision of Prof. Gerhard Brewka at Leipzig University.

Professional activities

My research interests include knowledge representation, logic programming, rule-based reasoning, multi-context reasoning, nonmonotonic reasoning, and (abstract) argumentation theory.

Currently, I am co-organizing the Fifth International Workshop on Systems and Algorithms for Formal Argumentation (SAFA 2024). In the InnoSale project, I managed tasks to represent TU Dresden as the work package lead for implementation.

On the practical side, I focus on Rust programming and maintaining a robust production system based on NixOS with flakes. Check out my projects: adf-obdd, my NixOS setup, and my solutions to all Advent of Code 2021 puzzles on GitHub.

Spare time

I voluntarily organized a weekly table tennis for employees as a Dresdner Hochschulsportzentrum (DHSZ) activity. It invited players of all levels to have a 90 minutes lunch break filled with a fun sport.

Jugger is my second favourite sport, which I try to practice at least weekly. It is a dynamic and agile team sport, combining strategic fencing elements with teamwork, where players aim to outmaneuver their opponents and score by placing a foam ball on the goal.

Alpine skiing is another occasional hobby of mine. I typically enjoy it during winter holidays in Austria.

I also have a large collection of Kickstarter-backed games, particularly enjoying exotic and complex titles.
