About Me

I am a PhD student (almost done) within the Security Group at the Computer Laboratory, University of Cambridge. My supervisor is Dr. Markus Kuhn and my research interests include authentication, EMV security, applied cryptography, side-channel analysis and digital communications.

My research is sponsored by Google and I am a recipient of the Google European Fellowship in Mobile Security. I've been a Google intern in the summer of 2011. In 2009-2010 I have done the MPhil in Advanced Computer Science within the Computer Laboratory, and previous to that I've been working as a research assistant at IRIT in Toulouse (France) with Romulus Grigoras and Vincent Charvillat within the Vortex team.

I am a member of Darwin College, where I was the captain of the football team ( I still join them from time to time). I am also part of the Christian Orthodox society in Cambridge.

I was born in Madrid, Spain and I did my undergraduate at the University "Politehnica" of Bucharest, Romania. During that time I won the Windows Embedded Student Challenge 2006 (now part of Imagine Cup) with my colleagues from Politehnica.

I also keep this page with a few tutorials about things I came across.


I presented our paper Chip and Skim: cloning EMV cards with the pre-play attack at IEEE S&P 2014. PDF.
