My research interests involve studies of global geochemical and biogeochemical cycles related to the lithosphere and hydrosphere using stable isotope tracers (S-O-H-C-Zn) and chemical methods. This interdisciplinary research integrates areas of low-temperature geochemistry and water-rock interaction, hydrogeology, environmental studies, and planetary geology. I am trying to integrate these fields in order to better quantify the chemical weathering of crustal rocks as a result of climate and to enhance knowledge and understanding of modern and past hydrological cycles on Earth and Mars. Furthermore, I attempt to elucidate human impacts such as acidification, land cultivation, and hydraulic fracturing on natural ecosystems.
Additionally, I have been using several field sites from New Mexico (e.g., White Sands gypsum dunes, Valles Caldera volcano, Rio Puerco watershed, volcanic terrains in Iceland) as terrestrial analogs for understanding the sources and formation timescales of hydrated sulfates on Mars.
My earliest research focused on the characterization of anthropogenic impacts on freshwater environments in Eastern Europe related to acid rain in mountain and lake ecosystems. I used multiple stable isotope tracers (S-O-H-C) to calculate the sulfate inputs from atmospheric acid wet deposition and I performed several incubation experiments to evaluate the buffering capacity of lake sediments in response to anthropogenic acidification of freshwater.
Stable Isotope Laboratory
I supervise the Stable Isotope Laboratory which is located in the Department of Earth and Planetary Sciences (EPS) on the campus of the University of Tennessee in Knoxville, Tennessee
We provide stable isotope services for research and commercial users. The lab has two Thermo-Finnigan Delta mass spectrometers and a variety of peripheral devices that enable the measurement of C-H-N-O-S isotopic ratios in a variety of materials. The types of analyses that we can perform and the prices per analysis are listed here.
