About me

I'm Marcos Alejandro García García, currently Tenure Track faculty at the Instituto de Física of the Universidad Nacional Autónoma de México. My research is primarily focused on the connection of particle physics and cosmology. This includes, among other things, the embedding of inflation into extensions of the Standard Model; the dynamics of dark matter production in the early Universe; the application of stochastic transport theory to inflation; the gravitational wave emission of the mergers of clumps of (axion) dark matter, and the phenomenology of Lorentz symmetry breaking.
