I am a CONACYT
Research fellow in Mathematics at CIMAT, in the City of
Guanajuato, Mexico, since may 2019. I belong to the CIMAT's Commutative Algebra and Algebraic Geometry
Academic Cluster.
I studied at the Institut de
Mathématiques de Jussieu (now Institut
de Mathématiques de Jussieu-Paris Rive Gauche) of the Pierre
and Marie Curie University (also known as UPMC, Paris 6, and now Sorbonne
University) from 2008 to 2015, under the joint direction of
Erwan
Brugallé and Jean-Jacques Risler.
I was a member of the research team
Analyse
Algébrique. My PhD thesis (Tropical intersection theory,
and real inflection points of real algebraic curves) can be
downloaded from here.

My areas of interest include:
- Algebraic and Analytic (non-Archimedean)
Geometry (Real Algebraic, Tropical Algebraic, Rigid
Algebraic and non-Archimedean Algebraic).
- Combinatorics (Matroids, Infinite Matroids,
Tropical mathematics).
- Differential and Tropical Differential Algebraic
Geometry.
- Inflection phenomena in Algebraic Geometry.
Right now I am very interested in the third subject. You can find
a comprehensive introduction to the state of the art on the
subject in our recent preprint Exploring tropical differential equations,
which grew up from the previous friendly introduction that can be
found here. (first version : march 2020)
More details on some of my ongoing research projects are
available in my Research Gate site.
