April 2016 - October 2017 student worker with teaching tasks at Technische Universität Berlin in Berlin
October 2014 - March 2016 student worker in the field of data acquisition at TEAS Germany GmbH in Berlin

Education

  • November 2018 - present:
    Ph. D. student in Computer Science at the Universität des Saarlandes, Saarbrücken, Germany and the Max-Planck-Institut für Informatik

    My current research focuses on the quality of publicly available data sources to reveal the Internet's logical structure as well as the mapping of this logical structure onto physical infrastructure. Apart from that I'm also interested in topics regarding route propagation, congestion inference, and content delivery.

  • November 2017 - October 2018:
    Master in Computer Science at the technische Universität Berlin

    Starting from October 2017 I pursued my master's degree in Computer Science at the Technische Universität Berlin. Since I developed a special interest in networks during my bachelor degree I choose 'Distributed Systems and Networks' as my major subject. The accompanying courses gave me the chance to better understand the full specturm of building blocks that today's Internet consists of; I learned about the Internet's control plane - which is where my interest for interdomain routing as well as congestion identification started from, the business related aspects that drove its current evolution, as well as how to configure the hardware that it runs on. To complement my theoretical knowledge I took projects that were closely related to research topics that reflected my interests. In one of those projects I analyzed the difference in congestion singals that can be derived from both explicit and implicit - RTT - signals. In my master thesis I collected Internet topology data from various sources, anlyzed their individual contribution, and evaluated different methods for inferring the Internet hierarchies top. After a year of study I received my master's degree in October 2018 with a final grade of 1.0.

  • October 2014 - March 2018:
    Bachelor in Computer Science at the technische Universität Berlin

  • August 2008 - August 2014:
    Abitur at the Strittmatter Gymnasium Gransee in Gransee

Hobbies

  • My girlfrind and I take care of a young Shiba Inu lady :)
  • I absolutely love TED talks.
  • I do have a strong interest in "cardistry" and the craft of performing coin and card magic. I also do own a small collection of rare playing cards.
  • I used to play table tennis. However, at the moment I do play only on an occasionally basis.
