Area of Expertise:Estimating agricultural water use in the Southwestern United States using GIS, remote sensing and field verification. Monitoring post wildfire runoff using the CSA method
Dickens, J.M., Forbes, B.T., Cobean, D.S., and Tadayon, Saeid, 2011, Documentation of methods and inventory of irrigation data collected for the 2000 and 2005 U.S. Geological Survey Estimated use of water in the United States, comparison of USGS-compiled irrigation data to other sources, and recommendations for future compilations: U.S. Geological Survey Scientific Investigations Report 2011–5166, 60 p., available at http://pubs.usgs.gov/sir/2011/5166/.
Area of Expertise:Ecology and Management of Rangelands
I study the impacts of woody plant encroachment into historic grasslands, specifically the influence of this large-scale land cover change on dryland decomposition and soil formation dynamics.
Area of Expertise:Ecosystem Services, Landcover Change, GIS
I am interested in understanding the impact of landcover change on the environment’s ability to provide ecosystem services. To do this, I am coming up with ways to map select ecosystem services across the Upper San Pedro Watershed, as well as looking for thresholds in water stress that causes vegetation to die off and landcover to change.
Area of Expertise:Disturbance regimes and impact on carbon cycling on high elevation pine forests
Field Assistant. Department of Ecology and Evolutionary Biology. University of Colorado, Boulder, CO.
Field Assistant. Department of Biology. Toolik Lake Field Station, University of Alaska, Anchorage, AK.
Area of Expertise:Phenology and the carbon cycle, hyperspectral imaging, drought
Title:Graduate Research Assistant
Area of Expertise:*
Area of Expertise:I’m interested in improving rain harvest for arid areas through experimental rain basins at Biosphere 2. Eventually, I will communicate my results to a wider professional and public audience to guide any large-scale implementation.
Area of Expertise:Developing an agent-based model of coupled human and natural riparian systems.
I completed a Master's at the University of Illinois studying the role of asymmetric competition on largemouth bass recruitment. During my time in Champaign,I also contributed to the development of a spatially-explicit food web model of the Upper Mississippi River.
I am currently developing an agent-based model of coupled natural and human ecosystems in the Southwest. Specifically, I am modeling how changes in ecohydrology influence human decision-making.
Title:Post Doctoral Research Scholar
Area of Expertise:Ecohydrology, Ecosystem Ecology, Terrestrial Carbon Cycle, Ecosystem Modeling
My primary research interest lies in understanding how above-ground and below ground plant processes are coupled as well as how plant-water relationship influence water and carbon flux across dryland and forest ecosystems and how external perturbations in the form of land use and climate change can affect the ecosystem dynamics at a landscape level.
Area of Expertise:Semi arid lands, land surface-atmospheric interactions, soil moisture-plant interactions, land surface energy budget
