My pictureI am an Assistant Research Professor (tenure-track) at the IMDEA Software Institute in Madrid, Spain. Before joining IMDEA Software, I held postdoctoral positions at Max Planck Institute for Software Systems (Germany), New York University (USA), and École Normale Supérieure (France).

In March 2010, I received a Ph.D. in Computer Science from University of Catania (Italy) under the supervision of Dario Catalano. During my PhD I was also a visiting student at New York University with Yevgeniy Dodis, and IBM Research T.J. Watson with Rosario Gennaro. See my CV for more details.


My research interests are in Cryptography and Security. In particular, my work focuses on the design of efficient and provably-secure cryptographic primitives and protocols. Some of the topics I work on include secure delegation of data and computation to the Cloud, homomorphic authenticators, zero-knowledge proof systems, and foundations of cryptography. See here for the full list of my publications.

I am looking for talented, highly motivated students, either graduate or undergraduate, who are interested in the area of Cryptography. If you are interested in working with me, please do not hesitate to contact me via email. I am currently looking for interns; please check the call.
