I'm a research scientist at the Institute of Space Sciences (CSIC/IEEC). My fields of interests are Astrobiology, Astrophysics and Instrument Design. My research focuses in the formation, and evolution of solar system minor bodies (comets and asteroids), the study of their fragments in space (dust, meteoroids) or as surviving rocks arrived to the Earth (meteorites). Undifferentiated asteroids provide clues on the origin of the solar system and on the formation and evolution of asteroids and planets because primitive meteorites were retentive of the chemical and isotopic conditions prevailing in the early solar system. The study of meteorites and micrometeorites, remote analyses of comets, and determination of dynamic strength from meteor data are complementary ways to gain insight on the structure and the physico-chemical properties of asteroids. My research group is focused in the study of asteroids and comets, and we use meteorites and sample returned materials to infer the physico-chemical properties of asteroids, particularly to promote Lunar and asteroid ISRU, and mining. We also study extraterrestrial rocks to understand the astrobiological role of meteorites in the origin of life. Our know-how on physical properties allowed me to join Stardust and DART NASA missions. I’m also a recognized expert on aqueous and thermal modifications of meteorites, their reflectance spectra and mineralogical composition of asteroids, and comets .
