José is an astrochemist in the Astrobiology Analytical Laboratory at NASA’s Goddard Space Flight Center. He works on the development of analytical methods to characterize, quantify, and measure the isotopic and enantiomeric signatures of small organic compounds (e.g. amines, monocarboxylic acids, and amino acids), that are present in carbonaceous chondrites, and that may have been relevant to the origins of life on Earth and possibly elsewhere. José is also a scientific Co-Investigator for the NASA Astrobiology Institute at the Goddard Center for Astrobiology and a Collaborator on the science team for the OSIRIS-REx asteroid sample return mission.
Ph.D. in Natural Products and Organic Chemistry (Dec 2009), Chemistry Department, University of Louisville, Kentucky, U.S.A.
B.S. in Chemistry (Dec 2003), Chemistry Department, Universidad Peruana Cayetano Heredia, Lima, Peru.
