Title: NASA Postdoctoral Fellow

Professional Biography:

I studied Physics at the Universidad Complutense de Madrid, in Spain (2008-2013). I specialized in Astrophysics with a Master’s degree at the same University (2013-2014), and then I moved to the Instituto de Astrofísica de Canarias to complete my Ph.D. studies (2014-2018) and participate in the operations and support of the GHaFaS Fabry-Pérot integral field spectrograph at the William Herschel Telescope (La Palma, Roque de Los Muchachos). In 2019 I joined the European Space Agency as a visiting scientist working for the Euclid Space Telescope, when I was selected as a NASA Postdoctoral Fellow in the Ames Research Center, in California, my current position. Here I am continuing my work with the Euclid mission, developing new space telescopes (DUNES), exploring the magnetic field of external galaxies (SOFIA), as well as the outer regions of galaxies (Chandra, VLA, GTC) using multiwavelength telescopes, from X-ray to radio, including optical, near and far-infrared observations.


Physics, Astrophysics.

Research Interests:

Calibration, operations, and instrumentation of Space telescopes, Galaxy Evolution, extra-galactic magnetic fields, galaxy mergers, and structure. Studying the effects of space environment on space telescopes.
