2017 - Ph.D. Cum Laude in Mathematics
Thesis: “Optimal Codes and Entropy Extractors”
Department of Mathematics, University of Trento, Ph.D. Supervisor: Prof. Massimiliano Sala
During my Ph.D. I mainly studied Coding Theory from both a Combinatorial and an Algebraic point of view. I spent a research period at LIRMM in Montpellier with Dr. E. Guerrini to work on optimal nonlinear codes.
Part of my research involved the link between Coding Theory and Entropy Extractors, algebraic methods useful to improve the entropy rate of Random Number Generators for cryptographic purposes. This work was carried out as part of the SiQuro Project.
2013 - M.Sc. Cum Laude in Mathematics
Thesis: “Algebraic Post-Processing and Non-binary Entropy Extractors”
Department of Mathematics, University of Trento, Supervisor: Prof. Massimiliano Sala
In my M.Sc. I studied Coding Theory, Cryptography, and the Mathematics related to them. After a research internship at IdQuantique SA where I worked on the analysis of Random Number Generators I worked on the Entropy Extractors from an algebraic point of view.
2011 - B.Sc. in Mathematics
Thesis: “La Formula di Hurewicz”
Department of Mathematics, University of Padua, Supervisor: Prof. Pietro Polesello
My B.Sc. was focused on pretty-much-everything-is-usually-taught-regarding-Mathematics-at-Bachelor-level. I studied the basics of Algebra, Analysis, Geometry, Probability and so on. For my B.Sc. thesis I presented a famous result of Algebraic Topology known as Hurewicz Theorem, a theorem linking the Fundamental Group, Singular Homology, Čech Cohomology and Singular Cohomology.
