Research Interests

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.

- GESTAR-USRA Visiting Research Assistant (July 2019 - Present)
Running GCMs to simulate Super-Earths and mini-Neptunes with hydrogen atmospheres around M-dwarfs. Simulating transit spectra and phase curves using the outputs of these GCMs.

- Center for Astrobiology NASA Goddard Space Flight Center, Summer 2018
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.

- Cool Worlds Lab Columbia University, Summer 2017 – Spring 2018
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.
