Sebastian Kappes

I'm a PhD student at the Internet Architecture Department of the Max Planck Institute for Informatics.
My research centers around network security, IPv6, and Internet topology.

Prior to joining MPI, I earned my M.S. and B.S. in Informatics from the Technical University of Munich,
where I was part of the organizing team of the Introduction to Operating Systems course and also served as a tutor for the IT Security lecture.
