Felix Fischer is a Research Associate and PhD student at the Chair 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.
Felix's work also considers ways of proving ethical machine learning, which includes attestation of private and fair models, as well as lineage and accountability of their decisions.
