I've submitted my thesis on the April 26 2018. Here's a visualization of my writing process:
Unfortunately, the submission was followed by my last day as an LMU employee shortly afterward.

Research Interests

Writing Progress:

I'm writing my dissertation. This is how far I am with writing up:

In a nutshell

With my research I am trying to facilitate decision-making for security and privacy related challenges on the user side.
I investigate these questsions:
  • How do we help users to cope with passwords in a more relaxed, user-friendly way?
  • Which mental models of password management drive user behavior?
  • Which persuasive design strategies are suitable for password support systems?
Keywords:
usable security, persuasion, nudging, decision-making, choice-architecture, passwords, user experience, persuasive technology, habits, behavior change.

Expected submission of dissertation: March April 2018

Password Metrics Tools

The password-metrics-csv package for npm offers a simple method to analyze a list of passwords. The list might originate from a user study. The output of the analyisis is a CSV file containing various metrics, e.g. the number of upper-/lowercase letters or the estimated number of guesses required to crack the password. Using this file, you can detect differences in experimental groups.
