Gabrielle De Micheli

About Me

I am a Senior Cryptographer at Beyond Aerospace Ltd. and have an affiliated research appointement as Visiting Scholar at UC San Diego in the Department of Electrical and Computer Engineering hosted by Prof. Farinaz Koushanfar.

My research focuses on the mathematical aspects of applied cryptography. My work lies at the intersection of Mathematics and Cryptography, with particular research interests for discrete logarithm computations in finite fields, lattice-based cryptography and computational number theory. I am interested in both attacks and defenses with a particular interest in using mathematical techniques for obtaining a better understanding of the security properties of commonly used cryptographic primitives in real-world applications.

Prior to this, I was a postdoctoral scholar at UC San Diego working with Daniele Micciancio in lattice-based cryptography and fully homomorphic encryption. I completed my PhD at the University of Lorraine, France, funded by INRIA working in the LORIA's team CARAMBA under the supervision of Pierrick Gaudry and Cécile Pierrot. I also worked at the University of Pennsylvania under the supervision of Nadia Heninger from 2016 to 2018.
