Montserrat Alsina

PhD in Mathematics from UB
Research areas: Number Theory, Algebra

Currently at UPC, I stay connected with UB (former position and PhD) and UAB (degree), through the Seminari de Teoria de Nombres (UB-UAB-UPC), where I have been in charge of coordination tasks during last years.

Main research has been about hyperbolic uniformizations of Shimura curves, related with quaternion algebras and quadratic forms. The PhD thesis, on that topic, received the prize Josep Teixidor de Matemàtiques 2000-2001, awarded by the Institut d’Estudis Catalans.

Current research is focused in applications on Coding theory, in relation with hyperbolic geometry and algebraic structures as quaternion orders, and quadratic forms.
