Dynamic iron redox transformations and their impact on contamination in groundwater - Athena Nghiem

Presentation by Athena Nghiem (University of Wisconsin- Madison) Athena is a Biogeochemist and Hydrologist who recently started as an Assistant Professor at the University of Wisconsin-Madison. Research Interests: Redox processes in Earth’s subsurface interact in complex ways, influenced by a range of hydrological, mineralogical, and biogeochemical factors. Athena’s research explores the scales of environmental variability in redox processes, spanning laboratory experiments to field studies, with a particular emphasis on data-driven and statistical methods to better understand and quantify these influences. Athena is studying how these factors contribute to the naturally occurring release of toxic arsenic into groundwater and she is interested in investigating existing mitigation strategies and their role in redistributing contaminants within the environment. This keynote lecture is aligned with the topical session, Microbial iron cycling and magnetic records of global change.
