Research Interests
O'Day's research is in the area of mineral-aqueous interface geochemistry as it relates to the chemistry and mobility of inorganic chemical species in the environment. She applies a variety of spectroscopic and microscopic techniques, in particular synchrotron X-ray methods, to studies of contaminant cycling, bioavailability, and remediation in natural systems.
Current research projects include:
- Arsenic speciation, cycling, and bioavailability
- Environmental influences on mercury speciation and methylation
- Novel methods for remediation of soils and sediments through application of reactive amendments
- Strontium and cesium uptake and release by weathering products related to radionuclide contamination at Hanford,WA
- Mechanisms and rates of abiotic and biotic uranium oxidation linked to nitrogen and iron cycling
Education
- Ph.D., 1992 — Stanford University
- M.S., 1984 — Cornell University
- B.S., 1981 — University of California, Davis
