IBM Research Zurich
I am a research staff member at IBM Zurich. Before, I was a postdoctoral researcher at Cornell Tech, New York, hosted by Rafael Pass. Prior to that, I was a postdoc in the Theory Group at University of California, Berkeley, hosted by Sanjam Garg. Previously, I did a PhD in the Crypto Team, at ENS, under the supervision of Michel Abdalla and Hoeteck Wee.
I work on cryptography at large. My research interests include building encryption schemes that provide a fine-grained access control, or permit selective computation on encrypted data. With my co-authors, I have also designed cryptosystems with scalable (tight) provable security guarantees. Lately, I have been fascinated by program obfuscation.
