arielanbar About arielanbar
Ariel Anbar is a Professor in the School of Earth & Space Exploration and the Dept. of Chemistry & Biochemistry at Arizona State University, where he also leads a NASA Astrobiology Institute team. Anbar’s group develops geochemical methods for many applications. Most relevant to this blog is research into the rise of environmental O2 – and of our aerobic biosphere – in Earth history. We want to know how the Earth wound up evolving creatures searching for other pale blue dots!
