Research and Teaching Interests

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 directs ASU's NASA-funded Astrobiology Program and the new 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 in 2015.   

 

Research Interests

My research program is grounded in the perspectives and practices of isotope geochemistry – a branch of geoscience in which careful and precise measurements of isotope ratios are used to learn about the world around us.

The activities of my research group are organized into three areas:

In basic research, we use chemical concepts and approaches – particularly the techniques of isotope geochemistry – to understand the geological, chemical and biological processes that sustain life at Earth’s surface, how they have changed through time, and how they might operate on other worlds. These investigations reveal the ebbs and flows of Earth’s history as an inhabited world, teach us about the complex relationships between life and environment, and help guide the search for life beyond Earth.

We are also deeply motivated by the application of basic research insights to make this world a better place. For example, the techniques of isotope geochemistry that we develop and use to study the ancient Earth turn out to be the foundation of a new class of “isotope biomarkers” that hold great promise for biomedical research and clinical application. These techniques also provide new ways of studying the human imprint on the modern environment. More broadly, basic knowledge about how planets sustain life provides pragmatic new perspectives on our role and responsibility as the first species to have intelligent control over the life support systems of “spaceship Earth”.

The focus of our education activities is to use innovative online teaching technologies to improve the science education of non-science majors. Most students will always major outside the sciences, yet in a democratic society it is vital that these future voters and leaders understand the nature of science. Our primary goal is to convey that science is not a collection of facts, but rather a process of narrowing the uncertainties in areas where the facts are not known. In addition, we aim to tighten the ties between cutting edge research and undergraduate education. Emerging digital technologies, when used creatively, can greatly facilitate these goals by engaging students in immersive, interactive, adaptive, and game-like simulations and lessons that bring students closer to real research experiences. Our thesis is that this type of pedagogy will do a far better job than traditional lecture-lab pedagogy in motivating students and modeling the authentic practices of science.
