    Our Research
    Our group uses laser spectroscopy to study chemical and physical processes that are important in Earth's upper atmosphere.

    For details on our current aeronomy experiments, check out our aeronomy page.

    Current Funding
     Our work on CO2-O vibrational energy transfer is supported by NASA Geospace Sciences and our work on O3-O vibrational energy transfer is supported by NSF's CEDAR program.
