Felix Fischer

Felix Fischer is a PhD student, and has been a Research Associate at the Professorship of Cyber Trust.

He studies the interaction of people with information security and privacy technologies. This means analyzing their application, usability and acceptance in the wild. His most recent publications focus on software engineers struggling with getting cryptography right and explore machine learning as a tool for usable security and privacy.

In his current projects, he investigates how machine learning can assist people in protecting their privacy. His goal is to develop systems that learn how to process data in a way that achieves both, increased utility and privacy for the individual user.
