No picture!!!  :-(

I am an associate professor (UHD) at the Institute for Logic, Language and Computation (ILLC) at the University of Amsterdam, Netherlands. I'm a member of QuSoft, the Dutch research center for quantum software, located at CWI, the Centre for Mathematics and Computer Science.

I am the chairman of the Talent & Outreach Committee of the Quantum Software Consortium (QSC).

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

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. Before that, I studied mathematics at ETH Zürich and wrote my Diploma thesis under supervision of Renato Renner and Ueli Maurer.
In 2015, I received a personal VIDI grant from Netherlands Organisation for Scientific Research (NWO).

I am a co-organizer of the 2020 edition of QCrypt from August 10-14 in Amsterdam. I have been a member and chair of the steering committee of the annual QCrypt conference, the 2018 edition took place in Shanghai, this year's edition will take place in Montreal. I have served on various program committees (EUROCRYPT 2019, AQIS 2018, PKC 18, CRYPTO 2017, TQC 2016, TQC 2015, EUROCRYPT 2015, QCRYPT 2014, SCN 2014, 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.

Since March 2018, I am on the editorial board of the Quantum Science and Technology journal, published by IOP.

I have been teaching various courses about cryptography and information theory at the University of Amsterdam. Since spring 2016, I have made positive experiences of teaching courses in fully-flipped-classroom style. Check, e.g., this report, or this interview.

In my spare time, I enjoy playing Ultimate Frisbee.
