Gabrielle 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.
Gabrielle Suissa is a Visiting Research Assistant working in the Planetary Environments Laboratory. Suissa is interested in exoplanet characterization, atmospheric modeling, exoplanetary interiors, and biosignatures.

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.

Constructed model to constrain core sizes of rocky exoplanets by exploiting boundary conditions. Parametrically interpolated two-layer interior models. Created and released public code (HARDCORE) capable of calculating the minimum and maximum core radius fraction given just planetary mass and radius.
