I am a Nordita Fellow working in gravitation and cosmology at the Nordic Institute for Theoretical Physics.
My research is directed towards finding new theoretical and observational approaches to the problem of cosmic acceleration and its connections to fundamental physics. You can get an overview of my work through the following links:
I am also the main developer of the hi_class code, a fast and flexible tool to test general Dark Energy models. I have also worked on other software implementations to test a variety of cosmological models.
My earlier research is contained in my PhD dissertation
"Probing the Foundations of the Standard Cosmological Model
and summarized in my
PhD defense presentation (shown below)
Whenever I find the time I also write popular science articles and the science blog "Persistencia y serendipia" (in Spanish).
