Teaching

If you are a student and interested in working with me on Internet-related projects (measurements, security), get in touch with me.

I taught both undergraduate as well as graduate computer science courses as Teaching Assistant (TA). During my time as PhD candidate I organized and managed TAs for large introductory computer science classes. I also co-supervised MSc/BSc theses.

  • Fall 2016: Introduction to Programming (Organization, TA Management)
  • Spring 2015: Data Structures and Algorithms (Organization, TA Management)
  • Spring 2014: Routerlab (Teaching Assistant)
  • Spring 2014: Internet Measurement Seminar (Organization)
  • Fall 2013: Network Protocols and Architectures (Teaching Assistant)
  • Spring 2010: Introduction to Computer Science II (Teaching Assistant)
  • Fall 2009: Introduction to Computer Science (Teaching Assistant)

Co-Supervised Theses (TU Berlin)

  • Martin Ott (BSc, 2016). “Measuring IPv6 Adoption by Crawling the BitTorrent DHT.”
  • Stefan Gerganov (MSc, 2015). “On the Suitability of Traceroute RTTs to Measure Geographic Distances.”

IPv4 Address Space Transfer Report

IPv4 addresses are now bought and sold on address markets. I collect transfer statistics from the Regional Internet Registries (RIRs) to generate an interactive report. See it here (hopelessly outdated – sorry!)
