Asmaa Boujibar, PhD
She/Her/Hers, Assistant Professor
Dr. Asmaa Boujibar is an assistant professor of Planetary Science. She recently joined both Geology Department and Physics & Astronomy Department of Western Washington University. She received her Ph.D. in 2014 from the Université Clermont Auvergne in France. She was a NASA postdoctoral fellow at the Johnson Space Center (2014-2016), then a Carnegie fellow at the Carnegie Institution for Science (2016-2021). Her research focuses on the formation of terrestrial planets in our Solar System and beyond, and the raw materials from which they form. Her projects use experiments in the laboratory and numerical modeling to replicate the high pressure and temperature conditions of planetary growth. She also applies machine learning algorithms, to improve our understanding of the formation of meteorite components and the chemical reactions occurring during planetary differentiation.
