Global Change | The Global Change Graduate Interdisciplinary Program

Viviana Barquero

I am an architect interested in sustainable communities and new urbanism, majoring in Arid Lands Resource Sciences minoring in Global Change. The interdisciplinarity of both programs has led her to focus her research primarily on the use of renewable energy as a way to mitigate climate change and improve livelihood conditions in Mexican arid regions.  

Glenn Schrader

Glenn Schrader’s research interests have focused on a broad range of areas in fundamental and applied materials science, with particular interest in catalysis. Most recently, he has studied the impact of complex catalytic processes on environmental sustainability. He has held visiting faculty appointments at the University of Queensland and the University of Sydney in Australia, and the Norwegian Institute of Technology and the University of Trondheim in Norway. While at Iowa State University he also held the position of senior chemical engineer within the U.S.

Christopher Scott

Christopher Scott is an associate research professor of water resources policy at the Udall Center for Studies in Public Policy, with a joint appointment as associate professor of geography and development. His work focuses on the policy dimensions of global change with particular emphasis on river basin management, including surface- and groundwater, urban wastewater reuse, and land use and urbanization impacts on water resources and quality.

David J. Schmidtz

David Schmidtz specializes in moral and social philosophy. Current projects include papers on instrumental reason, justice, environmental conflict resolution, civil society and the state, and the purpose of moral theory. He is the Director of the Arizona Center for the Philosophy of Freedom.  He teaches in the Departments of Philosophy and Economics and holds a courtesy appointment in the McGuire Center for Entrepreneurship at Eller College of Management. 

Yolande L. Serra

Yolande Serra specializes in tropical ocean-atmosphere interactions and atmospheric dynamics on daily to multi-year time scales. She is currently researching tropical east Pacific synoptic waves and their relationship to the underlying ocean and larger scale atmospheric circulations. Synoptic waves are the dominant scale of variability in low-level winds, precipitation, and clouds throughout the tropical east Pacific region, and are the primary source of east Pacific hurricanes.

Thomas Sheridan

Thomas Sheridan is the curator of ethnohistory at the Arizona State Museum. His research interests include contemporary ranching and rural development and the political ecology of ranching in the Southwest. His work involves documentary history and ethnographic studies, with projects focusing on a farming community in northwestern Mexico, Arizona history, the Mexican community in Tucson, the northern and southern frontiers of the Spanish empire in the Americas, and the Seri Indians.

James Shuttleworth

Jim Shuttleworth's major research interests include physical processes in hydrology—with an emphasis on evaporation and hydrometeorology—as applied to environment change at local, regional, and global scales. This work includes effects on global climate due to Amazonian deforestation and African desertification. Present research involves the representation of heterogeneous land surfaces in global climate models, the application of remote sensing methods within hydrology, and the micrometeorology of natural semi-arid vegetation and riparian systems in the desert Southwest.
