Research Interests

My current research focus is in the area of security and privacy with a particular interest in a holistic view on the examined systems. In particular, my research interests include, but are not limited to (naturally there will be an overlap between some of the topics):

Usability and Human behavior

It is important to design usable systems since otherwise improved security or privacy features won't be accepted by the users. On the other hand, usability is not the only factor deciding if a user accepts a certain system. I investigate how much certain factors influence the users' acceptance of privacy enhancing technologies and security measures.

Serious Games and Gamification

I aim to enable users to detect and defend social engineering attacks and privacy violations, to regard security considerations and to understand privacy implications. For that purpose, I develop and evaluate Serious Games and gamify processes and systems to improve user engagement and productivity.

Privacy-Enhancing Technologies

I investigate the development of secure and privacy-friendly architectures and practical solutions, such as anonymous e-commerce or the application of privacy patterns within fog and cloud computing environments. In particular, one of the re-occurring challenges is to make use of Privacy-Enhancing Technologies without degrading performance or usability.

Modeling & Measuring Privacy and Security

Security Management

Applied Crytography

I am also interested in applied cryptography for security and privacy purposes and the development of (crytographic) attacker models to get further insights about the chances of attackers to successfully break crytographic systems.
