Biography

Sebastian is a doctoral researcher in the Centre for Doctoral Training in Cyber Security at the University of Oxford. As part of the Systems Security Lab (SSL), run by Professor Ivan Martinovic, he researches the security of the physical-layer of a variety of large and complex systems, such as vision-based intelligent and automotive systems.

He started to specialise on Cyber Security during his undergraduate studies in Computer Science at the University of Applied Sciences Würzburg-Schweinfurt, Germany. Due to his interests in the security of modern cars, he completed his bachelor's degree with a dissertation at the research and development centre of the Dr. Ing. h.c. F. Porsche AG. Before his doctorate, he received a master's degree in Computing & Security and got awarded the prize for the best overall performance on the MSc in Computing & Security for the academic year 2017/18 from King's College London.
