Pedro Branco

Short Biography

I am a PhD student in Information Security at SQIG in IST, Lisbon. I am supervised by Paulo Mateus.

During Fall 2019, I visited Nico Döttling at CISPA. During Fall 2018, I was a Fulbright scholar at the University of Cincinnati, under the supervision of Jintai Ding. I am one of the founders of the Student Seminar SQIG. If you want to give a talk to our group, please contact me.


I am mainly interested in cryptography. More precisely, I am interested in post-quantum and theoretical cryptography.
