I am interested in the characterization of exoplanet atmospheres, from both a modeling and observational perspective. My focus has been on small gaseous planets, with a goal to characterize observable signatures of a surface through these planets' atmospheres. I have also been conducting a survey of uniformly observed and analyzed transmission spectra for Neptune-sized exoplanets with the Magellan Baade telescope.
