About me

I am a doctoral student in the research group of Prof. Wressnegger. I did my B.Sc. in 2015 at the Hochschule Furtwangen University. After three years as Software Engineer and Software Architect for embedded multiprocessor devices I decided to come back to the university. I finished my M.Sc. in Computer Science at the Karlsruhe Institute of Technology (KIT) in Sep 2020. My studies were concentrated on IT-Security, Cryptography, Anonymity and Privacy and Algorithm Engineering.

As a doctoral student my research is focused on machine learning and it's application in IT-Security. This includes for example vulnerability discovery, intrusion detection and malware detection. Therefore I use the explainability and interpretability of machine learning methods. I am interested in, how explainability can lead to better results in classification of virtual artefacts, like emails, images and communications. How can explainability help us to quantify the robustness of a learned model and how we can attack explanations. Beside all the interesting applications also the theoretical backgrounds allure me.

Convention of the Scientific Staff

As a member of the Convention of the Scientific Staff I am happy to receive your emails regarding any suggestions for the future development of the KIT's organization.


In my spare time I founded the hackerspace e.V. in 2016 and several other clubs, e.g. to promote local musicians. I love open source software and open hardware projects in general. This includes little arduino projects but also my homebrew relay cpu project EuroTwo. In addition I'm working on mechanical projects, using CNC mills or 3D printers, or I organize events like CodeGolfings, LightningTalks, Hackathons, Hackerjeopardyparties, or Cryptoparties. Further i'm an active ham radio operator with the call sign DO1NPX. You can find me in the university ham radio group DF0UK. If you are interested in sports, you can find me as a trainer in the underwaterrugby team of the SSC Karlsruhe as well as the KIT university team.
