Jay F. Nunamaker

Dr. Jay Nunamaker is Regents and Soldwedel Professor of MIS, Computer Science and Communication.  He is Director of the Center for the Management of Information and the National Center for Border Security and Immigration (BORDERS) at the University of Arizona.

Juan B. Valdes

Juan Valdes' research interests include stochastic and deterministic hydrology, flood forecasting, mathematical models of natural resources systems, modeling of space-time precipitation, environmental risk assessment, and stochastic modeling of environmental processes.

Katherine G. Morrissey

Katherine Morrissey’s research on the North American West focuses on the region’s environmental, social, cultural, and intellectual history. She is currently writing a book on environmental mining conflicts in the early twentieth century, examining the legal, scientific, and political struggles over mining debris and smelter smoke pollution.

Robert Varady

Robert Varady has examined environmental and water-management policy in arid regions—with a transboundary emphasis—especially in the U.S.-Mexico border area.  He has studied transboundary aquifer governance and is a consultant to UNESCO and FAO the GEF-FAO global groundwater governance project.  Varady has more than 100 publications on environmental history and policy and is past president of the International Water History Association (IWHA).

Marc L. Miller

Marc Miller’s environmental work highlights topics at the intersection of law and biology, with special attention to the concepts of conservation and sustainability, and to the relationship between science and environmental policymaking and environmental decisions.

Marvin Waterstone

Marvin Waterstone's current interests focus primarily on the intersections of discourse and power, and the uses of social theory. In addition, he maintains an active research and teaching program in issues of environmental and resource management and the human dimensions of global change.

David Meko

David Meko's research centers on improving the understanding of temporal and spatial variability of climate on time scales of years to centuries, and on applying knowledge of long-term climate variability to management of water and other natural resources. His specialty is time series analysis of tree-ring data. His current research projects address hydroclimatic variability in the Mediterranean region and the Sierra Nevada of California. 

Tracey Osborne

Tracey Osborne's research focuses broadly on the social dimensions of climate change mitigation, particularly in tropical forest ecosystems. She has worked extensively on issues of livelihoods, land access and local development as they relate to forestry-based carbon offset projects in Chiapas, Mexico. More recently, her work has explored the intersection of carbon finance, forms of governance, and livelihood benefits for small-scale carbon producers in the developing world.

Jake Weltzin

Jake’s interests encompass 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 USA-NPN.

Mitchel McClaran

Mitchel McClaran (PhD ’86, UC Berkeley) is Professor of Range Management where he teaches and researches rangeland ecology and policy. He is a Fellow in the Bart Cardon Academy for Teaching Excellence, College of Agriculture and Life Sciences, University of Arizona, and was the recipient of the Outstanding Teaching Award from the Range Science and Education Council in 1999. He is also the Assistant Director of the Arizona Agricultural Experiment Station in the College of Agriculture and Life and Director for Research at the 21,500 ha UA Santa Rita Experimental.  Range.
