Homepage of Urs Wagner

I am working on my Ph.D. as a member of the Applied Algebra Group of Prof. Joachim Rosenthal at the Institute of Mathematics of the University of Zurich. My main interest lies in Cryptography, with a focus on lattice-problems and the according complexity results and algorithms.
