Research topic
My master's thesis project focuses on analyzing the electron-phonon (e-ph) coupling of Th-fcc under pressure, taking into account electronic correlation effects (Hubbard) on its incipient 5f electrons, and studying in detail how the e-ph coupling is affected by variations in the Hubbard interaction.
Research topic
My research topic focuses on modulating the electronic properties and lattice dynamics of double-perovskite materials through the construction of solid solutions in order to enhance or suppress the electron-phonon coupling, using density functional theory and linear response theory methodologies.
Research topic
My PhD research project is focused on the theoretical study of the electronic properties of twisted-bilayer graphene (TBG) together with 2D transition metal-dichalcogenides (TMD), and how the proximity of the TMD could affect the TBG properties, specially when the spin-orbit coupling is being taken into account.

Research topic
The bachelor-thesis project was based in the analysis of the lattice dynamical properties of Th-fcc under pressure, including strong-correlation effects (Hubbard) on its incipient 5f-electrons, and analyze how such additional interaction modified the phonons and the anomalies already observed for Th.
Research topic
The bachelor-thesis project was based on the study of the dynamical stability of transtition-metal(TM) carbides as the TM content is changing on the crystal. The idea behind the project was that the superconducting properties of the TM carbides could correlate with the presence (or absence) of phonon anomalies on the phonon dispersion, and eventually to the ocurrence of phonon instabilities.
Research topic
The project was based on the hydride-superconductors family (with Tc has high as 200 K at 170 GPa), analyzing their superconducting state induced by a combination of electron-doping and applied pressure. Some of the properties analized were the Eliashberg function, the electron-phonon coupling parameter, the superconducting critical temperature, and the isotope effect, among others.

Research topic
The thesis was about the study of graphene and graphene-like systems, as silicene and germanane. The properties under study were mechanical, lattice dynamics, electron-phonon coupling, and superconductivity, among others.
Research topic
My thesis proyect was related to hydrogen storage materials, specifically analyzing the effect of electron doping on the stability of metal hydrides, in particular looking on their vibrational and thermodynamical properties by ab-initio methods.
Research topic
My thesis work was based on the study of Ac-Th light-actinides alloy, in particular analyzing the evolution of lattice dynamics and electron-phonon (e-ph) coupling properties as a function of doping concentration, applying density functional perturbation theory (DFPT) and the Eliashberg formalism.
Research topic
My Master tesis was related to the study of the relativistic effects (mainly spin-orbit coupling) on the vibrational and electron-phonon (e-ph) coupling of actinide (Ac), applying density functional perturbation theory (DFPT) and the Eliashberg formalism for the calculation of the e-ph coupling properties.
Research topic
My thesis was focused on the study of magnetism effects on the vibrational properties of the Ni-Cu magnetic alloy, and how the full-phonon dispersion and force constants relations are affected by magnetism.
