My current research is three-pronged, focusing on: (1) refining and optimizing methods for identification and quantification of gaseous oxidized mercury in air, (2) characterizing and quantifying plant-soil relationships in old fields in arid shrublands undergoing restoration, and (3) identifying controlling factor(s) on organic carbon-mineral associations in soil environments.

On this project, I coordinated and executed uranium aqueous chemistry field research at the Department of Energy Rifle, CO Integrated Field Research Center. I managed and assisted with various projects and collaborated with national and international research teams to collect, process, compile and organize data for publication. I utilized analytical techniques (e.g. KPA, IC, UV-Vis, XAS, EM) to probe the behavior and fate of uranium, and other contaminants, as a function of redox potential in an in situ groundwater system experiencing several treatments.

My graduate research focused on biomineralization and biosorption involving bacteria. I investigated the effects of non-metabolizing bacteria on the precipitation of metal phosphates and proposed a novel mechanism of biomineralization in a uranium-phosphate system. I utilized many techniques (e.g. XRD, XAS, ICP-OES/MS, SEM, TEM, TOC) to gather geochemical and visual data. I also investigated the effects of various ligands (e.g. chloride, fulvic acid) on mercury behavior in the presence and absence of a variety of non-metabolizing bacteria (e.g. Gram+, Gram-, obligate anaerobes). Thermodynamic modeling of the batch adsorption data was conducted to generate stability constants and Kd values for the mercury-bacterium interactions.
