Patrick Brosi
I studied history for two semesters in Tübingen and then switched to computer science. After obtaining my bachelor's degree in Tübingen and my master's degree in Freiburg I worked as a software developer for 2 years. I joined the chair of Algorithms and Data Structures as a scientific assistant in 2016 and worked on my PhD from 2017-2022.
