Hello! I'm Markus Toran, a security researcher and more.
In my free time, I enjoy hiking, board games, and CTF and experimenting with new programming languages. Feel free to connect with me!
I went to school in Karlsruhe, first to the Helmholtz-Gymnasium and later to the Carl-Engler-Schule, graduating there in 2018.
After school, I studied computer science at the KIT. I completed my bachelor degree in november 2021 with a thesis about verification of fairness properties for seat appointment methods. During my masters, I focused on IT Security. I wrote my master's thesis about IT Security and User Experience in the domain of Digital Identities.
After uni I worked as a security consultant at Secorvo in Karlsruhe. Currently, I am working as a researcher at Fraunhofer SIT in Darmstadt.
I hope, my work will contribute to a more secure digital future.
Selected peer-reviewed publications and other published work.
