Research Interests:

My research interests lie at the intersection of agriculture, ecology, and hydrology. I am especially interested in drought and the “life-cycle” of water in the western United States including water resource variability from mountain snowpack and rainfall and its impacts on agricultural production, ecohydrological processes, and surface mass and energy exchange. I use a variety of empirical techniques from my background in plant physiology, micrometeorology, and remote sensing. I also use various process-based models at spatial-scales ranging from the individual plant, to agroecosystems, watersheds, and the continent.

Degrees:

Ph.D. Plant Physiology and Micrometeorology 2014 Colorado State University, CO, USA
M.S. Forest Physiology and Ecology 2010 Oregon State University, OR, USA
B.S. Horticulture 2006 University of Florida, FL, USA

Postdoctoral Training:

2016-2019: Great Basin rangeland restoration ecology. US Geological Survey, Forest and Rangeland Ecosystem Science Center.

2014-2016: Montane and subalpine ecosystem ecology, snow hydrology. Institute of Arctic and Alpine Research and Boulder Creek Critical Zone Observatory, University of Colorado, Boulder.
