Who am I?

  • Currently, I am Marshall H. Stone Visiting Assistant Professor at the Department of Mathematics and Statistics at UMass Amherst (US).

  • In August 2021 I will be starting as an Assistant Professor in the mathematics department of NCSU.

  • Organizer, together with Alejandro Morales and Annie Raymond, of the Discrete Math Seminar at UMass Amherst! Check our page here!

  • AMS Simons Travel Grant Award 2020

  • Co-organizer of the online conferences AlCoVE (June 15-16, 2020) and FPSAC 2020 (July 6-24, 2020)

What do I work on?

My research has its starting point in the intersection of algebraic combinatorics and representation theory and expands to other areas from there. For instance, the symmetric functions as a way to understand character theory for the symmetric group and the general linear group, the combinatorial properties of different orders on permutations as tools to describe the multiplication of the Schubert classes in the cohomology ring of the Grassmannian , or the invariants in the shuffle algebra that give us the description of the invariants for multidimensional series in stochastic analysis. Arising from other areas, these problems involve combinatorial objects and structures that I want to study.

I am interested in symmetric polynomials from a combinatorial point of view. More precisely, I study symmetric polynomials appearing in other areas trying to understand the combinatorial objects that encode them. For instance, I have worked on Macdonald polynomials and their specializations and I am currently working on understanding the multiplication of Schubert polynomials and the e-positivity of the chromatic polynomials. Moreover, I'm interested in the structural constants that comes from representation theory, such as the Kronecker coefficients or the plethysm coefficients.

Recently, I have also worked on signatures of paths and their relation with the shuffle algebras, and on an insertion algorithm for diagrams algebras.

Where was I before?

  • From July until December of 2018, I was postdoc at the Max Planck Institute (Leipzig, Germany) as part of the Nonlinear algebra research group.

  • From July 2016 until June 2018, I was postdoc at York University (Toronto, Canada).

  • In April 2016, I defended my thesis at the Universidad de Sevilla (Seville, Spain), under the supervision of Emmanuel Briand and Mercedes H. Rosas.
