Overview

Alberto Fairén is an interdisciplinary planetary scientist and astrobiologist, specializing in geochemistry, mineralogy, hydrogeology, sedimentology and environmental microbiology of extremophiles, with a particular focus on understanding the habitability of early Mars and the search for life on Mars and ocean worlds. His work has been achieved through multi-disciplinary collaboration with researchers from around the world, and is published in 150 papers and 300 communications at international conferences. See Alberto's work featured in the Cornell Chronicle, in Research Outreach, and in the EU Research magazine.
