I am Francisco Villaescusa, mostly known as Paco. I am a research fellow at the Center for Computational Astrophysics in New York. I did my Ph.D. at the Instituto de Fisica Corpuscular in Valencia, Spain. I have been a visiting graduate student at the Canadian Institute for Theoretical Astrophysics (CITA) and the Institute for Theory and Computation (CfA/Harvard University). After completing my Ph.D. I was a postdoctoral researcher at the Astronomical Observatory of Trieste, Italy.
I am a theoretical astrophysicist working on several aspects of cosmology. I investigate the properties of the large-scale structure of the Universe with the goal of using cosmological observations to learn about fundamental physics. I am particularly interested in understanding the impact of neutrino masses on cosmological observables, that I study combining analytic techniques and state-of-the-art numerical simulations. My research also involves investigating how cosmological and astrophysical information can be extracted from 21cm intensity mapping surveys. I am part of the Square Kilometre Array collaboration, where I co-lead the simulations group. I have also worked on other topics such as the Lyman-alpha forest, modified gravity, BAO reconstruction, kSZ and galaxy formation and evolution.
