This post presents a poster of mine presented at the poster session of the 9th Algorithmic Number Theory Symphoisum.
My name is Felix Fontein and I'm currently a software developer at Dybuster AG. Until February 2014, I used to be a postdoctoral fellow at the University of Zurich. I'm working in the area of Computational Number Theory, in particular on arithmetic in global fields, the infrastructure of such fields, computation of regulators and fundamental units, and related areas. I studied at University of Oldenburg and at the University of Zurich, and was a postdoctoral fellow at the University of Calgary before going back to Zurich.
