Maximilian Golla

Postdoc at the Max Planck Institute for Security and Privacy in Bochum, Germany

Hi there!

I'm a postdoctoral researcher interested in usable security and privacy. While I studied computer science, I later specialized in information security and developed an interest for usability and human factors in computer security.

During my PhD, I focused on exploring the usability and security of password-based user authentication. At the time, I was a scholar of the DFG (German Research Foundation) research training group UbiCrypt. I worked extensively with Blase Ur from SUPERgroup at the University of Chicago and Adam J. Aviv from GWUSEC Lab at the George Washington University. I received my PhD in 2019 from Ruhr University Bochum, where I was advised by Prof. Dr. Markus Dürmuth.

Since October 2019, I'm a postdoc at the Max Planck Institute for Security and Privacy in Bochum, Germany. The research of our group at MPI-SP focuses on computer security, privacy, and human-computer interaction (HCI). We are especially working on methods to help users make better security and privacy decisions, as well as, to make complex computer systems more usable for non-technical users.
