Julian Funk

I studied computer science at FAU Erlangen-Nürnberg.
Currently, I am a PhD candidate in the System Security group.

My research interests are focused on trusted execution environments, confidential computing, software isolation, and systems programming.

If you are enrolled as a computer science student at FAU, I can directly supervise your bachelor's /  master's thesis or master's project. Note that most available open theses are not publicly advertised. You can always write a kind email (german or english) containing some information about you to julian.funk@fau.de and we'll chat for available options.
Additionally, if you are interested in my topics, you may also want to consider thesis options from my colleagues, Jonas Röckl and Matti Schulze.
