Biography

Ariel Anbar is a scientist and educator interested in Earth’s evolution as an inhabited world, and the prospects for life beyond. His major focus is the deep time history of O2 and bioessential metals in the oceans, as deduced from the application of novel techniques in isotope geochemistry to ancient sedimentary rocks. Trained as a geologist and a chemist, Anbar is a President’s Professor at Arizona State University, where he is on the faculty of the School of Earth & Space Exploration and the School of Molecular Sciences, and a Distinguished Sustainability Scholar in the Global Institute of Sustainability. The author or co-author of over 100 refereed papers, Anbar directed ASU's NASA-funded Astrobiology Program from 2009 - 2015. Recognized as an education innovator, he now directs ASU's Center for Education Through eXploration. He is a graduate of Harvard (A.B. 1989) and Caltech (Ph.D. 1996). Before coming to ASU he was on the faculty of the University of Rochester from 1996 to 2004. Anbar is a Fellow of the Geological Society of America, which awarded him the Donath Medal in 2002. He was recognized as an HHMI Professor in 2014, and elected a Fellow of the Geochemical Society and the European Association of Geochemistry in 2015.
