I am a Post-Doctoral Researcher at the Chair of Communication and Distributed Systems at RWTH Aachen University (Germany). I began my studies in Computer Science at RWTH Aachen University in 2002 and graduated with Diploma degree (equiv. M.Sc.) in 2009. I then joined the Chair of Communication and Distributed Systems as a Researcher and PhD Student. In July 2015, I completed my PhD.

During my studies, I received a short-term study diploma (with honours) at the University of Kent at Canterbury (England) in 2006. My stay abroad was supported by the Erasmus exchange program. I worked on my diploma thesis at the Helsinki Institute for Information Technology (HIIT) in Finland supported by a scholarship of the Deutscher Akademischer Austausch Dienst (DAAD) in 2008. My Diploma thesis covers the topic of providing efficient identity-based security functions on in-network elements and was awarded with the Ericsson-UMIC-Diploma Thesis Award in 2009. My PhD thesis revolves around the topic of resource-conscious network scenario for the embedded Internet of Things. My research interests comprise mobile and wireless networking, secure end-to-middle communication as well as efficient network security for the IP-based Internet of Things. I am actively involved in the standardization process of security-related topics at the Internet Engineering Task Force (IETF).

As part of my work at COMSYS, I was and still am involved in the acquisition, the organization, and the development of several third-party funded research projects. The list below shows the funded research projects that I have actively contributed to during the project phase.

SensorCloud (2012 - 2014)

funded by BMWi within the Trusted Cloud framework
The project SensorCloud is a collaboration of the Chairs of Computer Science 3 and 4 at RWTH Aachen University, with three partners from academia and industry. It is a joint effort to securely integrate two recent trends in computer science: the Internet of Things (also known as Cyber-Physical-Systems) and Cloud Computing.

Mobile ACcess (2009 - 2012)

funded by Ziel2.NRW and the ERDF of the European Union
The project Mobile ACcess is a collaboration of the Chairs of Computer Science 4 and 8 at RWTH Aachen University with seven municipal and industrial partners including the cities of Aachen and Monschau. It is a joint effort to show the feasibility and practicability of a city-wide network consisting of individual access networks united by a novel concept for Wi-Fi sharing communities.

In the past, I have been working with a number of passionate, highly motivated, and gifted students. The list below shows all submitted student theses that I have (co-)advised. The supervisor for all these theses was Klaus Wehrle. I would like to thank all of the people listed below for their great work and their valuable contributions to my dissertation and to the specific research project in focus of their thesis.
