Current Research

I conduct research to quantify atmospheric-biospheric interactions, including the use of eddy covariance technology to study the exchange of trace gases (carbon dioxide, water, ozone) between the atmosphere and the earth's surface (vegetation, soil, and snow). I also research issues involving the physical processes governing CO2 transport in soils and snowpacks and the impact of fire on soil physical properties and microbial populations.

Research Interests

Develop a better understanding of an ongoing spruce beetle epidemic can have on carbon and water cycles at a high elevation subalpine forest.Develop physically-based computer models to improve predictions of and insights into the long-term impacts on soils that extreme heating during a prescribed burn or wildfires can cause.

Past Research

My research focuses on some of the long-term impacts that relatively short-lived, but extreme, events or environmental conditions can have on vegetation and soils. Such events alter ecosystem benefits and resources, such as the potential for carbon sequestration, stream flow amounts and timing, and soil water availability, for decades to centuries. Quantifying these impacts on water and carbon is critical for long-term resource planning and sustainability.

Why This Research is Important

** Theory and practice of eddy covariance(1) A perspective on thirty years of the Webb, Pearman and Leuning density corrections ,(2) The canopy horizontal array turbulence study (CHATS) ** Carbon cycling and climate Climate control of terrestrial carbon exchange across biomes and continents **Fire and soils Advancing investigation and modeling of first-order fire effects on soils ** Beetle impacts on high elevation siteEvapotranspiration response of a high elevation Rocky Mountain (Wyoming, USA) forest to a bark beetle epidemic
