Short Bio

I am a Senior Researcher at the Security and Cryptography Laboratory hosted by Professor Serge Vaudaney.

Prior to EPFL I was a Post Doctoral Research Associate in the Computer Science department at the New Jersey Institute of Technology as part of the Cybersecurity Research Center working with Professor Reza Curtmola and Professor Qiang Tang. Before NJIT I was affiliated with the Electrical and Computer Engineering department at the University of Arizona, as a member of the Wiser lab, directed by Professor Ming Li. I hold a Ph.D degree from the Paris Institute of Technology, hosted in EURECOM under the supervision of Refik Molva within the Applied Cryptography and Security Protocols lab.

See that bird? It is a brown-throated thrush, but in Germany it is called a thrush, and in Chinese they call it a chung ling and even if you know all those names for it, you still know nothing about the bird. You only know something about people; what they call the bird. Now that thrush sings, and teaches its young to fly, and flies so many miles away during the summer across the country, and nobody knows how it finds its way.
