For the past two years, I have held the post of postdoctoral research associate at the Departamento de Física, Centro Universitario de Ciencias Exactas e Ingenierías, Universidad de Guadalajara. My current studies mainly focus on cosmology of the early universe, as well as primordial gravitational waves, and the exact solutions of cosmological models; additionally, my research has been expanded to the dark energy model building from a purely geometric standpoint.
