  • Brief Bio

    Vincent Kofman is a postdoctoral associate working with dr. Geronimo Villanueva on advancing the Planetary Spectrum Generator to model high temperature exoplanet atmospheres. 

    During his Ph.D. at the Sackler Laboratorium for Astrophysics in Leiden, Vincent developed and build an experimental setup to spectroscopically characterize astrophysical ice mixtures, with a particular focus on water ice and embedded organic molecules.
