You just keep on trying till you run out of cake.
I work on Internet measurement and analysis to better understand how this giant system works that connects us all.
In very broad terms I am interested in network systems, on both small and large scales. I also require practical problems to solve since I am not much of a theoretician.
I am currently working on evaluating the differences between data and control paths on the Internet. While it is expected that traffic is routed according to the information announced via the Border Gateway Protocol (BGP), in practice, the actual path taken might deviate. Identifying where these differences occur helps our understanding of the Internet as a global system.
Another topic of interest are video streaming systems, in particular virtual reality video streaming.
I studied computer science at Saarland University in Saarbrücken (Germany). I completed my B.sc. in 2018 after writing my thesis at Björn Brandenburg's Real-Time Systems Group at the Max Planck Institute for Software Systems . For my master's thesis I looked at how to improve video streaming performance by dropping parts of the video. This work was finished in 2020 at Anja Feldmann's Internet Architecture Group at the Max Planck Institute for Informatics . I have continued working as a research assistant at MPII before joining IIJ-II in 2021.
