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. 

Positions/Employment


Post-doctoral researcher

American University - NASA Goddard Space Flight Center

September 2018 - Present

Incorporating state-of-the-art spectroscopic databases into the Planetary Spectrum Generator to simulate exoplanet atmospheres. Assessing detectability of molecular species in exoplanet atmospheres using both high-resolution ground-based spectroscopy and low-resolution with upcomming space telescopes.


Doctor of Philosophy

Leiden Observatory - Leiden, the Netherlands

September 2014 - August 2018

Designed and build an experimental setup to study the chemistry and physics in interstellar analogues. 


Royal Dutch Academy of Science Research Fellow

Utrecht University - Utrecht, the Netherlands

February 2013 - November 2013

Developed methods to map elemental abundances in resin-embedded sediments using micro-XRF.
