- Post-doctoral Research Ecologist, USDA-ARS, Jornada Experimental Range
Primary Research Interests:
The primary focus of my research is to understand how ecosystem properties and processes change in response to anthropogenic impacts, in particular land-use and climate change. My research examines the spatial distribution and variability of ecosystem properties and processes from the microscopic to landscape scale. Current areas of research include:
- Multi-temporal remote sensing techniques for assessing landscape condition.
- Development of a near real-time drought monitoring framework for natural resource management across the Western United States.
- Development of rapid, quantitative protocols for assessing ecosystem disturbance using infrared spectroscopy.
