The origin of life on Earth (and possibly elsewhere) was either influenced by or a product of organic compounds from space. These vital compounds were delivered by comets, meteorites, and IDPs to the early Earth. Such material is delivered today. Our goal is to analyze the organics in such samples at unprecedented sensitivities. Our focus is on small organic molecules, such as amino acids, hydroxy acids, amines, purines, pyrimidines, pyridines, etc.  We typically use different forms of chromatography coupled with various types of mass spectrometry to understand the structural, enantiomeric, and stable isotopic distribution of these species across a range of extraterrestrial materials—principally meteorites.  We furthermore closely collaborate with field work and other laboratories to perform experiments to explore the origin of these compounds under plausible astrophysical conditions.  Principally we study aqueous alteration, energetically processed ices, gas-grain reactions, and terrestrial analogs of Mars.
