    Gabrielle Suissa is a Visiting Research Assistant employed by GESTAR/USRA at NASA GSFC working in the Planetary Environments Laboratory. She is interested in exoplanet characterization, atmospheric modeling, exoplanetary interiors, and biosignatures.

    Suissa's current work primarily focuses on running GCMs (global circulation models) to simulate potentially habitable planets around M stars. She also works on simulating transit spectra from GCM outputs to assess how detectable these planetary systems would be. Modeled exoplanets of interest include terrestrial Earth-sized aquaplanets and super-Earths/mini-Neptunes with hydrogen dominated atmospheres.

    Positions/Employment

    7/2019 - Present

    Visiting Research Assistant

    GESTAR-USRA, NASA GSFC

    Runs GCMs to simulate Super-Earths and mini-Neptunes with hydrogen atmospheres around M-dwarfs. Simulates transit spectra and phase curves using the outputs of these GCMs.

    5/2018 - 8/2019

    Undergraduate Research Associate

    Goddard Center for Astrobiology, NASA GSFC

    Simulated exoplanet transmission spectroscopy for ocean-covered earth-like planets synchronously rotating M- and K-type stars. Used GCMs as inputs to radiative transfer model in order to create and analyze spectra. Conducted exposure time calculations for TESS targets based on spectral trends.
