VIOLETTA WEGER
UNIVERSITY COLLEGE DUBLIN
ABOUT
I am currently a postdoctoral researcher at the University College Dublin in the group of Professor Eimear Byrne. I completed my Ph.D. in Mathematics under the supervision of Professor Joachim Rosenthal at the University of Zurich. My research interests include cryptography, algebraic coding theory and number theory.
