Summary
I am a research associate in the Computational Logic and Argumentation group. My research interests include
- Argumentation
- Explainable AI
- Hybrid AI/ Neuro-symbolic AI
- Uncertain Reasoning
- Inconsistency Tolerance
- Knowledge Graphs
- Applied Optimization
- Algorithm engineering and analysis
Before joining Imperial in 2022, I had previous academic positions at
- the Analytic Computing group at the University of Stuttgart (Research & Teaching, 2020-2022),
- the Artificial Intelligence group at the University of Osnabrück (Research & Teaching, 2016-2020),
- the Knowledge-based Systems group at the University of Hagen (PhD student & Research assistant, 2011-2015)
and spent research visits at
- the Automata Theory group at the University of Dresden (3/2019),
- the Intelligent Systems group at University College London (2/2017 and 3/2018),
- the Artificial Intelligence group at the University of Mannheim (12/2015),
- the Research Centre for Knowledge and Data at the University of Bolzano (11/2015).
Since 2016, I gave more than 20 courses in the area of Artificial Intelligence. My teaching portfolio includes courses on
- Artificial Intelligence (Introduction and Advanced),
- Probabilistic Reasoning,
- Nature-inspired Algorithms,
- Multiagent Systems,
- Knowledge Graphs,
- Time Series Analysis and Forecasting.
Before studying Computer Science (2005-2010), I worked in Electronics (2000-2001) and Logistics (2001-2004). After finishing my MSc, I worked as a software engineer on Enterprise resource planning (2010-2011) before starting my PhD.
