Current Research

My current research interests involve response of microbial community to temperature changes along an latitudinal gradient in alpine and subalpine ecosystems of the Southern Rocky Mountains and Sky Islands of the Southwest. I am also studying response of microbial community to fuels/fire risk reduction treatments and wildfire, and the associated processes that are microbially mediated such as N mineralization, decomposition, and carbon sequestration.

Research Interests

My research interests include microbial community dynamics, nutrient cycling in soils, and disturbance affects on nutrient cycling.

Past Research

Soil nutrient and microbial responses to tree densities as modified by mechanical thinning and/or prescribed fire in ponderosa pine and woodland ecosystems.

Why This Research is Important

Alpine and high altitude spruce ecosystems may experience shifts due to temperature increases with global climate change earlier than other ecosystems.
