Short CV

Since June 2013, I am a researcher and Ph.D. student at the Chair of Communication and Distributed Systems. I received my master's degree in computer science at RWTH Aachen University in April 2013. As a member of the Network Architectures group, my research interests lie in scalable and adaptive networks, as well as in content distribution and realization of services for constrained, opportunistic and traditional networks. Currently, I am working in the MAKI project, which aims at developing scalable and adaptive mechanisms for the future Internet. 

Projects

netray.io Internet Observatory

As member of the network architectures group, i'm also contributing to the Internet Observatory operated by our group. One goal of this observatory is to study the Internet-wide adoption and usage of (new) Internet protocols by utilizing large-scale measurements. Such measurements are necessary since the Internet as one of the most complex systems ever built is not fully understood. Exemplary, we analyze QUIC, HTTP/2, and TCP initial windows in the Internet. More information and results are available at netray.io.

HTTP/2 Server Push

Currently, the web is experiencing a major protocol shift from HTTP/1.1 to HTTP/2. Among several new techniques used in HTTP/2, Server Push has the potential to reduce the overall page load time by allowing the server to push content to the client without an explicit request. To evaluate the overall HTTP/2 adoption and the use of Server Push, we conducted a large scale measurement study. More information and results are available at push.netray.io.

PowerGraph

The basis for this project was a thesis supervised by Jan Rüth and me. The goal is to provide an affordable and mobile power monitoring solution for mobile devices. The resulting device, named PowerGraph, is realized as an extension board for the Raspberry Pi (B+). More information, e.g., the hardware schematics and the developed software, can be found here
