Bio

I am a PhD student in mathematics at Complutense University of Madrid. My advisors are María Alberich-Carramiñana  and Alejandro Melle-Hernández. In 2019, I have done a 1 month research stay at Centro de Investigación en Matemáticas (CIMAT) in Guanajuato, México, and a 2 and half months research stay at Technische Universität Kaiserslautern in Kaiserslautern, Germany. My main interests are about singularities of curves, using techniques of algebraic geometry, commutative algebra and topology and also numerical semigroups. I focus my study in two areas: analytic invariants of planar curves and morphisms and numerical semigroups and its combinatorics.

I also like dissemination of science. I collaborate with the radio program El zoo de Schrödinger at Inforadio Ucm. In addition, I am one of the founding members of the project Cometas of dissemination of mathematics at the Faculty of Mathematics in Complutense University of Madrid.

 

Research interests

Algebra, geometry and topology. Deformations of isolated singularities. Analytic and topological invariants of isolated singularities.
