My name is Nicolás Loayza Romero, I am originally from Quito, Ecuador. I completed my undergrad with a Physics BsC from Universidad San Francisco de Quito, Ecuador. I participated in the Diploma programme of the International Centre of Theoretical Physics (ICTP) in Trieste, Italy. I completed the programme in the High Energy, Cosmology and Astroparticle Physics section with the supervision of Paolo Creminelli. I am currently a PhD student at Universitat de Val'e8ncia working under a contract with CSIC and the supervision of Daniel G. Figueroa. My main research interests are related to the physics of the early universe and cosmology, in particular the gravitational wave imprints and our ability to study these scenarios with lattice simulations.
