Dr. Julien de Wit’s primary interest and expertise lies in the field of data science, where he believes that math and science are brought together to make sense of newly accessible pieces of reality. Over the past five years, he has developed and applied new analysis techniques to map exoplanet atmospheres, study the radiative and tidal planet-star interactions in eccentric planetary systems, and constrain the atmospheric properties and mass of exoplanets solely from transmission spectroscopy.
