Short Biography

I'm a postdoctoral researcher at COMSYS.

My main research interests center around Internet measurements and network protocol performance.

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.

PowerGraph

The basis for this project was a thesis supervised by Torsten Zimmermann 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.
