About Greg

My research interests include the use of geochemical mineral weathering products, elemental and isotopic (Ca, Sr, and C), to study seasonal and long-term changes in the terrestrial Arctic systems. These tracers allow unique insight into the connections between the geosphere, hydrosphere, and biosphere, to understand how northern Alaskan soils and rivers will respond to amplified Arctic warming and the implications for the global carbon cycle. I am also interested in the further development of high-precision isotope methods to further increase the resolution and functionality of Ca and Sr as geochemical tracers.
