Dr. Elmar Tischhauser

I am a professor for infomation security in the department for mathematics and computer science at the University of Marburg. Previously, I was working as a Chief Cryptographer for Cybercrypt A/S and an Associate Professor in Cybersecurity at DTU Compute, the department of mathematics and computer science at the Technical University of Denmark. Earlier, I was an F.W.O. research assistant and a postdoctoral researcher at ESAT/COSIC, KU Leuven with Vincent Rijmen.
