Current Research

2017-Present: Postdoctoral Scholar, University of Nevada, Reno
My current efforts are aimed at understanding the soil characteristics that are coupled with restoration success in abandoned agriculture fields in the salt deserts of Nevada, and what effect(s) restoration efforts have on soil functions, including the resistance and resilience of the soil to common local perturbations.

Past Research

2016-2017: Postdoctoral Scholar, University of Nevada, Reno
My research focused on the effects of in situ iron oxide minerals on the stability of soil organic carbon in temperate forest soils. I utilized varied analytical techniques (e.g. UV-vis, TC, EA, XAS, FT-ICR-MS, XRD) to characterize Fe-C relationships, and collaborated with team members and partner research teams to probe the interactions between iron oxides and carbon as a function of varied biogeochemical parameters. I also worked with colleagues to develop a project investigating the stability of iron oxide-complexed organic matter in soil to understand the extent to which coprecipitation of iron oxides and organic carbon can stabilize labile carbon compounds.

Fall 2011: Research Assistant & Site Manager, Stanford Linear Accelerator Center
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.

2007-2012: Graduate Research Assistant, University of Notre Dame
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.
