About:

I am the PI of a Conex-Plus Marie Skłodowska-Curie grant at Universidad Carlos III de Madrid (UC3M). My research encompasses several areas, including field theories with boundaries, general relativity, quantum entanglement, atmospheric physics, and Quark-Gluon plasma formation.  I have published 19 papers, with 13 in Q1 journals and 16 as the corresponding author (CA).


I obtained my PhD in 2017 from the Benemérita Universidad Autónoma de Puebla (BUAP), Mexico with a CONACyT scholarship. I was also part of one research project founded by CONACyT. I developed geometric methods to analyze regular and singular field theories defined on regions without boundaries. After my PhD, I was invited to be a researcher at BUAP for 18 months. During that time, I worked on the gauge symmetries of gravitational theories. I taught 4 undergraduate courses in Physics and Mathematics, and 3 graduate courses in the Master’s program in Physics. I also contributed to the preparation of the study program of 4 courses at BUAP. In this stage of my career, I grew into an independent researcher, pursuing my own lines of research, which are different from my work as a PhD student, and stopped collaborating with my PhD advisors.


My next objective was to incorporate boundaries into the Lagrangian and Hamiltonian formalisms, leading me to collaborate with a group at the Consejo Superior de Investigaciones Científicas (CSIC) and UC3M. This collaboration resulted in a postdoctoral position at the CSIC for two years, funded by the Mexican government. During my time at the CSIC, we developed a geometric version of the Dirac algorithm that effectively deals with systems with boundaries and provided a powerful tool to avoid the common problems encountered in such systems. We also found a generalization of the Husain-Kuchar action that can induce gravitational models on the boundary under certain circumstances. I also expanded my research to applied topics like the atmospheric Lapse rate.


The previous scholarship required me to return to Mexico to work. There, I got the most prestigious Postdoctoral position in Mexico (for two years) at the Universidad Nacional Autónoma de México (which ranks highly in world rankings based on the university's extensive research) where I worked on topics related to quantum properties such as purity, von Neumann entropy, and entanglement. I also got a grant funded by CONACYT. I left this position after six months to accept a Marie-Curie-CONEX-plus fellowship at UC3M (funded also by the European Commission through the Marie-Sklodowska Curie Actions). Our recent works studied the Hamiltonian Formulation of parametrized unimodular General Relativity, consistent deformations of gravitational theories, edges observables and states of the Maxwell-Cher-Simons theory, and Poisson brackets in loop quantum gravity. I have also extended my research lines to cover the liquid behavior of the Quark-Gluon Plasma, quantum entanglement, and the spatiotemporal propagation of COVID-19.
