Hilairy Hartnett

Professor of Geological Sciences and Professor of Chemistry: Arizona State University

Hilairy Hartnett (Assoc. Prof.) is jointly appointed in the Schools of Earth and Space Exploration and Molecular Sciences (formerly the Dept. of Chemistry and Biochemistry) at Arizona State University. She is also a Senior Sustainability Scientist in the Julie Ann Wrigley Global Institute of Sustainability and co-directs the ASU PlanetWorks Initiative. She is a sea-going oceanographer and organic geochemist whose research focuses on Earth systems and Exoplanetary systems and time scales that range from seconds to millennia. She and her students explore carbon and nitrogen cycling in diverse aquatic systems including: urban wetlands, rivers, hot springs, and oceans. She applies field- and lab-based techniques to investigate the processes and feedbacks that transfer of elements (i.e., C, N, and P) and energy between biological and geochemical systems. More recently she is developing ideas and approaches for building consensus among scientists, technologists, governance, and stakeholders around planetary-scale climate intervention. She is fundamentally an ‘interdisciplinarian’ and is often surprised by the things that she now includes among her expertise.
