Maxime Ruaud

Professional Biography:

Dr. Ruaud was born in France in 1990. He completed a master degree in astronomy and astrophysics in 2013 at the Paris-Meudon observatory and obtained a PhD in astrophysics in 2016 at the laboratoire d’astrophysique de Bordeaux in France. His PhD was focused on the modeling of the physical and chemical processes at work in the interstellar medium and especially on the interplay between gas and dust. His expertise is grain surface chemistry, theoretical astrophysics and computational modeling. His main project is to study the effects of gas-grain chemistry in protoplanetary disks alongside Dr. Gorti.


– PhD, University of Bordeaux (France), 2016

– M.S. in Astronomy and Astrophysics, Paris – Meudon Observatory (France) 2013

– B.S. in Physics, University of Rennes 1 (France), 2012
