I am currently working as PhD student in the area of secure distributed applications. The main focus of my work is on Darknets, overlays that restrict communication to devices of users sharing a real-world trust relationship. In this fashion, they prevent Sybil attacks and large-scale surveillance by design.
However, due to their restricted connectivity, Darknets lack efficiency. In my thesis, I evaluate, improve, and design various methods such as network embeddings and virtual overlays for efficient routing in Darknets. Graph theory and complexity theory are important tools for analyzing the suggested algorithms, as are network simulations.
Before joining the Privacy and Data Security group at TU Dresden in 2014, I was a member of the P2P  Networks group at TU Darmstadt and a PhD scholar of CASED, the Centre of Advanced Security Darmstadt, under the supervision of Thorsten Strufe. I received my diploma in Mathematics with Computer Science from TU Darmstadt in 2011, and was awarded the Datenlotsenpreis for my thesis 'Analysis of Routing in Sparse Small-World Topologies' in 2012. During 2009, I worked as a student researcher at the University of Saskatchewan, focusing on Genetic Programming under the guidance of Prof. Simone A. Ludwig.
