Short Biography

I am a Research Geologist at the Geologic and Environmental Change Science Center in Denver, CO. The overarching objectives of my research are to (1) describe and quantify natural biogeochemical processes at the Earth's surface and (2) determine how these processes will respond to climate and/or landuse change. Many biogeochemical processes are often dominated by exchanges between the lithosphere, hydrosphere, atmosphere and biosphere. Over long timescales, the flux of matter and energy shapes both the physical structure and chemical composition of the Critical Zone and over shorter timescales, these features determine how the system responds to disturbances. Developing a mechanistic understanding of the processes controlling these fluxes is essential for predicting and managing the function of environmental resources and the sustainability of agricultural systems.

Biogeochemistry of the Critical Zone

Image of Current Focus for Biogeochemistry of the Critical Zone

My current research is focused on understanding the controls on the long-term storage and stability of organic C in soils and the role of water flux in soil biogeochemical processes. Specifically, I am interested in how long timescale processes such as soil development influence soil C cycling and the nature of linkages between terrestrial and aquatic C cycling.  To address these research topics, I use an array of traditional biogeochemical measurments, isotopic tracers and mathmatical models.
