Foteini Baldimtsi


I am a Phd student in the Computer Science Department at Brown University under the supervision of professor Anna Lysyanskaya. My research interests are in cryptography, security and data privacy with a special focus in electronic cash and anonymous credentials systems.

I spent the semester of Fall 2013 as an intern at Microsoft Research in Redmont, WA working in the Cryptography group with Melissa Chase. Before, I spent the summer of 2012 as an intern in the Cryptography and Security group of IBM Research in Zurich working with Jan Camenisch, Anja Lehmann and Gregory Neven.

You can find my CV here.

A blog post describing how can we get private, secure and efficient payments for public transportation.
