About Me

Computer Scientist, Researcher, Doctoral Candidate

I am a Computer Scientist

Currently, I am finishing my dissertation topic on privacy-preserving location-based service for a 2021 submission.

In March 2012, I joined the Telekom Innovation Laboratories in Berlin as a doctoral candidate. As a research scientist in Prof. Dr. Axel Küpper's chair Service-centric Networking, I contribute to TRESORCurcumaPARADISEIdentityChainDIMS, and IDunion. My main research areas are location-based services, applied security, privacy-preserving technologies, access control policies, self-sovereign identity, and distributed ledger technologies.

In 2008, I started to work as a research assistant at the University of Reading in England for nearly three years. I joined the EU-funded Hydra Middleware project (now LinkSmart middleware) in the School of Systems Engineering. My main focus was on security/policy aspects and context-awareness functionalities during the Hydra software realization and work on project demonstrators and general research.

In 2002, I finished my diploma thesis during a student identification and authentication project at the IT-Service-Center (now Zentraleinrichtung Campusmanagement) of the Technische Universität Berlin, where I worked as a student research assistant. The main focus of the thesis was on e-mail encryption and smartcard security.

After receiving my diploma, I continued working at the tubIT Service Center (ZECM) in Berlin as a research assistant. During this time, I contributed to security, policy, and access control projects, such as TUBIT and OBAN.
