No picture!!!  :-( I am an assistant professor (UD) at the Institute for Logic, Language and Computation (ILLC) at the University of Amsterdam, Netherlands. I collaborate with Harry Buhrman's Quantum Computing group at CWI, the Centre for Mathematics and Computer Science.

I am currently looking for a PhD student in quantum cryptography.

In 2010, I received a personal VENI grant from Netherlands Organisation for Scientific Research (NWO).

I did my PhD in the Cryptology Group at BRICS, Computer Science Department of  Aarhus University. My PhD advisors were Louis Salvail and Ivan Damgård.
I studied mathematics at ETH Zürich and wrote my Diploma thesis under supervision of Renato Renner and Ueli Maurer.

My research interests are Quantum Cryptography, Cryptographic Protocols, and (Quantum) Information Theory.

I will be serving in the program committee of SCN 2014. I was in the program committee of CRYPTO 2013, QCRYPT 2013, ICITS 2012, QIP 2012, QCRYPT 2011, ICITS 2011, WISSEC 2010 and the cryptography track of RSA 09. I was co-organizing a workshop on Cryptography from Storage Imperfections, held in March 2010 at Caltech.

In November 2012, I taught the course Introduction to Modern Cryptography at the University of Amsterdam.

In my spare time, I enjoy playing Ultimate Frisbee.
