Foteini Baldimtsi


As of Sept. 2014 I have joined Boston University working as a postdoctoral researcher in the BU Security group. My research interests are in cryptography, security and data privacy with a special focus in electronic cash and private authentication techniques. 

I received my Ph.D. from Brown University in 2014 where I was supervised by Anna Lysyanskaya. During my time at Brown I was fortunate to spent a semester at Microsoft Research in Redmont, WA working in the Cryptography group with Melissa Chase and a summer at IBM Research in Zurich working as a member of the Cryptography and Security group.

You can find my CV here.

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