Joel A Biederman    Research Hydrologist Joel A Biederman/ARSUserFiles/49407/Joel Headshot 2024.JPGResearch Hydrologist Southwest Watershed Research Center USDA-Agricultural Research Service 2000 E. Allen Road Tucson, AZ  85719 Tel: (520) 647 - 9236 https://nature.arizona.edu/joel-biederman
https://www.researchgate.net/profile/Joel_Biederman
http://tinyurl.com/googlescholar-jabiederman Research Interests I am a Research Hydrologist with the USDA-ARS Southwest Watershed Research Center.  I work to understand the impacts of climate and land use changes on watershed services and to develop new tools for sustainable watershed management.   I specialize in 1) interactions of ecosystems and hydrology, 2) ecosystem disturbances such as drought, fire and logging, 3) snow hydrology and 4) leveraging research results from diverse sites to address questions of regional to global scale. Current Projects Quantifying the sensitivity of dryland ecosystems to climate change using long-term measurements of carbon dioxide and water exchanges between ecosystems and the atmosphere
Measuring the impacts of drought, beetle infestation, and wildfire on water resources of the Western US
Understanding the interactions of climate, topography and forest management on snowpack and snowmelt-derived water resources Education and Background I grew up spending school years in rainy McMinnville, Oregon, but my family worked summers in Arizona, where I learned about the role of water in dryland ecosystems.  I received degrees in Civil and Environmental Engineering from Montana State University and conducted water and wastewater research at the NSF Center for Biofilm Engineering.  After serving as a teacher in France and then Connecticut, I returned to Arizona in 2010 to pursue a Ph.D. in Hydrology and Water Resources with advisor Paul Brooks at the University of Arizona.  After four years as a postdoc with Russ Scott at SWRC, I was hired as a Category 1 scientist in 2018.
