I am a Beatriu de Pinós postdoctoral fellow at Centre de Recerca Matemàtica in the group of Marta Casanellas using algebraic methods to address questions in Phylogenetics.

Previously I was a postdoc at the Mathematical Statistics group led by Mathias Drton at TU München and at Max-Planck-Institut in Leipzig in the Nonlinear Algebra research group of Bernd Sturmfels. Before that, I spent some months at TU Berlin in the framework of the Thematic Einstein Semester on Algebraic Geometry.

I obtained my PhD in 2019 at Universitat de Barcelona on approximating local rings by Gorenstein rings under the supervision of Joan Elias.

My main research interests lie in the realm of Algebraic Statistics and its applications to Life Sciences, using tools from Commutative Algebra, Algebraic Geometry and Computational Algebra.
