Jake Weltzin

Jake Weltzin assumed his position as Executive Director of the USA-NPN in August 2007. Jake’s interest in natural history developed as he grew up in Alaska and served as an exchange student in the Australian outback. He obtained his B.S. from Colorado State University, M.S. from Texas A&M University, and Ph.D. from the University of Arizona. Following a post-doctoral fellowship at the University of Notre Dame, Jake went to the University of Tennessee, where he served as Assistant and then Associate Professor.

Jake is interested in how the structure and function of plant communities and ecosystems might respond to global environmental change, including atmospheric chemistry, climate change, and biological invasions. His research spans temperate and tropical grasslands and savannas, temperate woodlands, deciduous forest, and sub-boreal peatlands. His recent experience as a science administrator at the National Science Foundation underscored the need to foster large-scale science initiatives such as the USA-NPN. As its first Executive Director, Jake’s vision for USA-NPN is “to develop a continental-scale instrument for integrative assessment of global change that simultaneously serves as an outreach and educational platform for citizens and educators.”
