Alex Bredariol Grilo is a CNRS researcher at Sorbonne Université (Paris, France). Before that, he was a postdoctoral researcher at QuSoft and CWI (Amsterdam, the Netherlands), a research fellow at the Simons Institute of UC Berkeley (Berkeley, USA), a PhD candidate at the Université Paris Diderot (Paris, France), and he did his undergraduate and master studies at the University of Campinas (Campinas, Brazil). Alex is interested in (quantum) complexity theory and (quantum) cryptography, mostly in the interplay of both. Some problems of particular interest are the Quantum PCP conjecture, verifiable delegation of quantum computation by classical clients, and the interplay between quantum computation and classical complexity theory.
