I am a PhD student at Saarland University, working as a PhD Candidate at the CISPA Helmholtz Center for Information Security. My research is focused on Web security as well as usable security for developers and is regularly published at top-tier venues (e.g. USENIX Security, ACM CCS, NDSS). You can find my papers on Google Scholar, in the ACM Digital Library, and in DBLP. To keep in touch with developers and security experts from the industry, I also regularly give talks about my research at industry conferences such as OWASP AppSec or RuhrSec.
In addition to that, I have taught other students as a tutor and teaching assistant in several different lectures, supervised topics in different seminars, and advised students in the process of their bachelor or master thesis or for study-related projects.
During leisure time, I regularly organize and participate in information security competitions called Capture the Flag (CTF) together with our team saarsec (saarsec|steg1) located at Saarland University. Moreover, I am also interested in sports, in particular Jugger at our university team Keulen Eulen.
