About me

My name is Raphael. I am a phd student, working as a research assistant at iNET research group at HAW Hamburg. My research focuses on Internet measurements & security, often using network telescopes as a vantage point.

So far my programming languages of choice have been C++ and Python. I think actors are a cool programming concept. While sometimes tedious, low-level networking is a really fun topic.
