Alex Bredariol Grilo obtained his PhD at the Université Paris Diderot, under the supervision of Iordanis Kerenidis. Before that, he did his master's and bachelor's studies in computer science at the University of Campinas, Brazil. Currently, Alex is a postdoctoral researcher at QuSoft and CWI, hosted by Ronald de Wolf and Stacey Jeffery. 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.
