I study how trace metals common in natural systems (many of which are micronutrients and contaminants) and mineral structures are affected during iron and manganese biogeochemical cycling, with the goal of understanding how biogeochemical processes at the mineral-water interface affect the compositions of natural waters in present day and geologic systems. I study both abiotic and biotic factors contributing to changes in mineral structures and trace metal speciation and uptake. My research combines my interests in inorganic chemistry, aqueous geochemistry, and biomineralization. I am currently studying fungal manganese oxides with my postdoctoral fellowship -- fungi are intimately linked to several geologic and environmental processes, such as element cycling, mineral formation and dissolution, rock weathering, soil formation, and the mobility of trace metals. I use wet chemistry techniques and bulk characterization methods, such as X-ray diffraction, Fourier transform infrared spectroscopy, and synchrotron-based X-ray absorption spectroscopy, in my research.
