Regents Professor, School of Geography, Development & Environment
I am a Professor in the School of Geography, Development & the Environment (SGDE) with joint appointments in the Laboratory of Tree-Ring Research and Geosciences, and faculty affiliations with Institute of the Environment, the Global Change Graduate Interdisciplinary Program, and the Arid Lands Resource Sciences Graduate Interdisciplinary Program. Most of my research focuses on understanding the hydroclimate of the past to inform current environmental and societal concerns, with a focus on major watersheds in western North America. While paleoclimatology is at the heart of my work, it inevitably extends to include the investigation and understanding of the current controls on hydroclimate. A strong component is the connection between the scientific aspects of my work and the challenges of managing natural resources (especially water) in the face of changing demands, climate extremes, and climate change impacts. Prior to coming to the University of Arizona, I was a physical scientist at the NOAA Paleoclimatology Program in Boulder, CO.
Director, Climate Assessment for the Southwest
Associate Research Scientist, Arizona Institutes for Resilience
I am an Associate Research Scientist and Director of the Climate Assessment for the Southwest (CLIMAS) program at the University of Arizona. A human-environment geographer, I contribute to and lead inter- and trans-disciplinary teams that conduct place-based, problem-oriented environmental research. The overarching goal of his work is collaborative development of relevant and useful knowledge to prepare for and respond to societal problems related to climate variability and change. My research generally falls into three categories: evaluation of use-inspired environmental research; development of theory and pragmatic approaches to socially-engaged environmental research; and development of knowledge about the social and cultural context for inter- and trans-disciplinary teams and the design and implementation partner engagement strategies.
School of Natural Resources and the Environment
I have worked to bridge the science-society interface through dialogues between scientists and decision makers and through collaborative projects that require environmental and climate science findings, data, and information. My research focuses on climate variability and change, drought, and adaptation to a changing climate. At the University of Arizona, I serve as Director of the Water, Society & Policy M.S. program in the School of Natural Resources and the Environment. I am also deputy director for science translation and outreach in the Arizona Institutes for Resilience. I am an affiliated faculty member in the University of Arizona's School of Geography, Development & Environment, Laboratory of Tree-Ring Research, and Udall Center for Studies in Public Policy. I also serve on the faculty advisory board for the University of Arizona's Center for Compassion Studies.
Assistant Staff Scientist
Climate Assessment for the Southwest (CLIMAS)
In 2008 I joined the Climate Assessment for the Southwest (CLIMAS) program at the University of Arizona. As a qualitative social scientist with training in geography and political ecology, my research interests center on the interactions between humans and their environments. Currently, I am investigating how to build an equitable local food system in Southern Arizona that will be resilient to future public health, environmental, and climate risks. My research portfolio also includes assessing climate adaptation strategies and evaluating how interdisciplinary and transdisciplinary CLIMAS research supports a thriving Southwest region. I manage the CLIMAS-sponsored Environment and Society Fellowship Program, which funds graduate students who are practicing socially-engaged research and science communication. Prior to working with CLIMAS, I worked with the University of Arizona's Bureau of Applied Research in Anthropology as an outreach coordinator for community-based, participatory projects in Nogales, Sonora and Arizona.
Department of Environmental Science
My research program includes developing a fundamental understanding of the fate and transport of contaminants in the environment, with a primary focus on plant-soil systems. In parallel, I am building citizen science programs to increase public participation in environmental health research, developing low cost environmental monitoring tools to improve exposure estimates, and designing effective risk communication and data report-back strategies to improve environmental health literacy.
