I am a Ph.D. student in Informatics at University of Lisbon (Informatics Departament @ Faculty of Sciences) in Portugal, and in Electrical and Computer Engineering at Carnegie Mellon University (Electrical & Computer Engineering Department @ College of Engineering) in the USA, in the scope ot the CMU|Portugal Program.
My current focus of academic research is in cryptography, mainly in secure two-party computation. I am also very interested in matters of Identity and Privacy.
My Ph.D. advisors are Alysson Bessani (@UL) and Nicolas Christin (@CMU).
