About Me
I am an assistant professor (Universitair Docent) for computer security in the
Digital Security Group at
Radboud University.
Until November 2012 I was a postdoc in the
Research Center for Information Technology Innovation
and the
Institute of Information Science of
Academia Sinica.
Before that, I was postdoc in the
Department of Electrical Engineering of
National Taiwan University within the
IntelNTU Connected Context Computing Center.
Before that, I was a postdoc in the
Institute of Information Science at
Academia Sinica.
Before that, I was a Ph.D. student in the
Department of Mathematics and Computer Science at
Eindhoven University of Technology.
In January 2011, I completed my Ph.D. at Eindhoven University of Technology in the Coding and Cryptology Group under the supervision of Tanja Lange and Daniel J. Bernstein.
In 2006, I finished my Diplom in computer science at RWTH Aachen University at the Institute for Theoretical Information Technology under the supervision of Rudolf Mathar and Michael Naehrig.
