I am a Technology Scout for Cyber Security with the Integrated and Advanced Software Solutions department at AVL List GmbH, an automotive engineering company with around 11k employees worldwide. My current task is the technical development lead of our automated cybersecurity testing platform, as well as to coordinate the research activities for the (automotive) cybersecurity domain. Before that, I was a key researcher with the Competence Group Cyber Security and Defence at the DIGITAL – Institute of Information and Communication Technologies of JOANNEUM RESEARCH. My further interests are security models, network security and cryptography. I have more than 15 years of experience in ICT security and earned a master's degree with distinction in "IT Technologies & business informatics" with the thesis "An approach to Securing IPsec with Quantum Key Distribution". I conducted scientific studies and engineering conceptualizing work on cyber-physical systems, as well as published various papers on diverse ICT security topics. I am a Certified Ethical Hacker and earned an ISO 27001 Information Security Manager certificate. Furthermore, I am a member of the Austrian Standards Institute working group for secure web applications ISO's technical committee 22/SC32/WG11 (responsible WG for developing ISO 21434), as well as the IEEE, the ACM and the SAE, and have served as scientific conference and journal reviewer and as evaluator for an H2020 project's open call. I'm currently also a technical expert project reviewer for the European Commission's Chip-JU research program. Also, I was teachning computer networks as a part-time lecturer at FH Campus02 University of Applied Sciences (2019-2024). Currently, I'm pursuing a PhD study on learning-based cybersecurity testing at the Mälardalen University.
Main research focus:
