William Conant

WIlliam Conant is a Research Professor in the Atmospheric Sciences Department with research interests in aerosol-cloud-climate interactions, radiative transfer in the atmosphere, global climate change, ocean heat budget/ocean-atmosphere interactions, and cloud-aerosol-biosphere interactions

Andrew Comrie

Dr. Andrew C. Comrie is an interdisciplinary climate scientist and geographer. His research is focused on connections that link climate with health, pathogens and vectors as well as atmospheric environmental issues in general. He has published widely in specialized and interdisciplinary international journals. His specific expertise includes climate and health, synoptic climatology, urban and regional air pollution, climate variability and change in the Southwest United States, and techniques for mapping climate and environmental information.

Andrew Cohen

Andrew Cohen studies lake deposits to interpret environmental and ecological history. He has used fossil and recent crustaceans and mollusks and sedimentary records to study a variety of subjects such as the geological history of lake basins, the evolution of endemic invertebrates that live in lakes, the history of human impacts on lake ecosystems and the use of long lake sediment drill core records to understand the environmental context of human origins. Most of his research has concentrated on lakes and lake deposits of the East African rift system.


Jonathan D. Chorover

Jon Chorover's research involves lab and field experiments on natural soils, estuarine sediments and constituent phases in aqueous systems in order to better understand their role in controlling biogeochemical cycles and environmental quality. Primary focus areas presently include organic chemistry of soils and sediments, macromolecule-surface interactions in bacterial adhesion, reactivity of radioisotopes (137Cs and 90Sr) in thevadose zone, and soil weathering (age and climate) sequences in Hawaii.

Nader Chalfoun

Nader Chalfoun's research interests include energy conservation, passive solar architecture, outdoor environmental comfort, green building materials, and sustainable architecture.

Christopher Castro

Christopher Castro’s research interests include climate variability and change, the North American monsoon, regional atmospheric modeling, and land-atmosphere interactions.  Current research within his group at the University of Arizona focuses principally on physical understanding and prediction of climate in North America through regional atmospheric modeling and analysis of observations.  His main research emphasis is the North American Monsoon.  As the Chair of the Geophysics Commission of the U.S. National Section of the Pan American Institute for Geography and History, Dr.

Paul D. Brooks

Paul Brooks' research interests focus on both basic and applied questions of ecosystem structure and function, especially with respect to how changes in terrestrial ecosystems affect surface water quality. Recent research projects have examined the effects of anthropogenic N and S deposition on high-elevation catchments in Colorado, climate change and precipitation patterns in seasonally snow-covered systems, the link between ozone loss, UV exposure and amphibian decline, trace gas fluxes from arctic ecosystems, and land use change on the recycling of soil carbon and nutrients.

David Breshears

Dr. Dave Breshears’ research focuses on the ecohydrology of drylands, including emphasis on the grassland-forest continuum (gradients of woody plant coverage that include shrublands, savannas, and woodlands, as well as grasslands and forests); wind- and water-driven erosion and associated transport; and especially drought-induced tree mortality as affected by warmer temperatures accompanying climate change.  Through this work he strives to enable improved decision making and management regarding issues of land use, pollution, and global change.

Paul Blowers

Paul Blowers has developed a method for estimating global warming potentials for chemicals using only computational chemistry methods. This approach uses theoretical chemistry to predict reaction kinetics with hydroxyl radicals and infrared spectra of the compounds. This information is aggregated to produce global warming potential estimates without even needing to manufacture the chemicals for testing. This approach has the potential for screening new chemicals for climate change before they are even created in a lab.

Eric Betterton

Eric Betterton's research focuses on atmospheric and environmental chemistry. This work includes urban air quality, ground water remediation, frozen solution chemistry, water isotopic chemistry, cloud condensation nuclei, and microphysical and chemical properties of winter precipitation.
