Welcome! Our lab works at the interface of soil science and biogeochemistry, pursuing research questions in soil carbon cycle-weathering feedbacks and redox cycling in upland soils. We use our understandings gained from this fundamental work to address the challenges we face in a world of rapid environmental change. Specifically, our work addresses two of the grand challenges in the environmental sciences: the global C cycle and water quality. The scale of our work spans from mineral interactions at the micron scale to tracking nutrient and element modulating reactions in soils across broad gradients that cross ecosystems. The lab’s analytical toolbox consists of both laboratory and field techniques, including traditional soil mineral extractions, field monitoring of elemental and nutrient fluxes, geophysical proximal sensing, and novel in situ sensor arrays. Our interdisciplinary approaches and interests lend themselves to diverse research questions, both applied and fundamental, poised to address soil’s role in modulating element and nutrient fluxes across scales.
See my page on OU School of Geosciences for my CV and personal research interests. I obtained my Ph.D. in Soil Science and Biogeochemistry from Penn State (co-advised in the Kaye and Brantley labs) and my M.S. in Ecology from the University of Georgia (in the Thompson Lab)
Diversity and Inclusion in the Hodges Lab
The Hodges Critical Zone Biogeochemistry Lab believes that everyone should have equal access to science, and we strive to create an environment that welcomes and respects diversity in all its forms—including cultural, racial, religious, age, gender identity, sexual orientation, physical ability, and mental wellbeing… more
