Biography
Hilairy Hartnett (she/her) has joint appointments in the School of Earth and Space Exploration and the School of Molecular Sciences. She earned an A.B. degree in chemistry from Vassar College in 1990, and M.S. and Ph.D. degrees in oceanography from the University of Washington. After postdoctoral work at Rutgers University, working in river and estuarine systems, she joined ASU in 2003. Her current research interests are in the areas of 1) biogeochemistry, specifically how geochemical, microbial, and anthropogenic processes affect elemental cycles in modern and paleo-environments, 2) Astrobiology and organic geochemistry, particularly how organic reactions are influenced by minerals under hydrothermal conditions and their implications for habitability, and 3) urban ecology and anthropocence science.
