My thesis focuses on the introduction of uranium into Ohio agricultural soils through the use of phosphate fertilizers. Uranium is a trace element that is often associated with P-fertilizer use, due to its natural occurrence in phosphate rock, and having the potential to accumulate in soils, crops, and surface waters. My study investigates the geochemistry of agricultural soils treated with P-fertilizer and compare them to the chemistry of agricultural soils that have been treated with other management practices (cover crop, manure application, etc.). Another component of my thesis involves characterizing historical Geographic Information System (GIS) data in order to correlate past uranium concentrations in Ohio soils with maps of the state’s geology, ancient glaciation, and land use/land cover.

Iron is the limiting factor for biological productivity within the Southern Ocean and by examining the amount of bioavailable iron within these sediments, we can assess whether glacial sediments are viable source of iron for productivity and possible implications of global warming.

I am examining the geochemistry of surficial soils from the Central Namib Desert in Africa. I analyzed the salt content of the major anions and cations concentration and how it varies as the sample move inland, which supports the notion that there is very little weathering that occurs.
