B.Sc. (4 yrs) in Mathematics (Ramo Cientı́fico – Matemática Pura) by Faculdade de Ciências e Tecnologia da Universidade de Coimbra (1995), M.Sc. in Mathematics by Faculdade de Ciências e  Tecnologia da Universidade de Coimbra (1998), Ph.D. in Sciences (Sp. in Mathematics) by Universidade do Minho (2002).

My scientific interests are in matrix theory, mostly generalized inverses but also connections to partial orders and operator theory. Other interests include cryptography, post-quantum cryptography, algebraic coding theory, having supervised various BSc/MSc projects on the topic, and I have recently been looking into applications to quantum codes.
