    Infrared instruments for future planetary exploration missions

    Technology investments and future planetary missions planning. Infrared astronomy. Development of mid and far-infrared sensors for the exploration of the outer planets and their icy moons.
    Leadership of International Workshop on 'Instrumentation for Planetary Missions"


    Research Experience:

    Cassini Mission to Saturn (1991-97): Development and characterization of flight Far Infrared (IR) detectors for the Composite Infrared Spectrometer (CIRS) instrument on board the Cassini spacecraft. Cassini arrived at Saturn on July 1, 2004.

    COBE Mission (1985-1989): Study the effects of ionizing radiation on the InSb, Ge: Ga focal plane IR sensors on board the Cosmic Background Explorer (COBE) (launched 1989).

    Cooled focal plane sensor arrays for a possible Infrared instrument on the reformulated Jupiter Europa Orbiter (JEO) mission


    Current Projects

    Space-borne instruments focal plane assembly development

    Magnesium Diboride Detector Array (MDA) Development for Infrared Instruments on Future Missions to the Outer Planets and their Icy Moons.

    Served as Principal Investigator for the following projects

    • "Cryogen free cooled IR focal plane detector for infrared instruments on the Jupiter Icy Moons Orbiter (JIMO)" project
    • "High Temperature Superconducting detector characterization with low Tc SQUID" project.
    • "Development of HTS and MgB2 detectors on monolithic sapphire membranes for future planetary exploration missions" project.
