Since 2023, Matías R. Bender has been working as a researcher (chargé de recherche) at the project/team Tropical at INRIA Saclay – Île-de-France - CMAP, École polytechnique in Palaiseau, France. Prior to this, he was a Postdoctoral researcher in the Algorithmic Algebra group at the Institut für Mathematik, Technische Universität Berlin, led by Peter Bürgisser. In June 2019, he earned his PhD from Sorbonne Université, under the guidance of Jean-Charles Faugère and Elias Tsigaridas.

Bender's research focuses on polynomial systems, where he studies algorithms for solving them and their applications in various domains. His PhD thesis specifically dealt with effective algorithms for solving sparse polynomial systems using Gröbner bases and Resultants.
