Anthony S. Wexler	Department of Mechanical and Aeronautical Engineering Department of Civil and Environmental Engineering Department of Land, Air and Water Resources	aswexler@ucdavis.edu
Dr. Wexler works on measuring and modeling particle dynamics in the atmosphere and in human airways. He develops a) new instruments for measuring composition and size of individual particles, b) mathematical models that link emissions to ambient air quality so that regulators can explore candiate emissions control strategies, and c) models of particle deposition in the human airway that link breathing characteristics and anatomy to regional dose and how airways change during development due to this dose. His research indicates that airborne particle size and composition close to freeways are significantly different than those particles greater than 100m from the freeway (Zhang, et al. 2004).

Charles Goldman	Professor of Environmental Science & Policy	crgoldman@ucdavis.edu
Together with other researchers in the Tahoe Research Lab, Dr. Goldman studies the efffects of road pollutants on eutrophication in Lake Tahoe. His research has shown that road dust is an important source of phosphorus pollution and that atmospheric nitrogen from local vehicle emissions are the primary source of nitrogen input to the lake.

Fraser Shilling	Staff Researcher, Environmental Science and Policy	fmshilling@ucdavis.edu
Mr. Shilling's road ecology related research includes the development of a habitat fragmentation and connectivity analysis of the Sierra Nevada foothills; GIS analysis to determine habitat suitability for a variety of native species. He has also been involved with the application of ecological information in decision-support for agencies involved with transportation system design, construction, and removal (Girvetz & Shilling 2003).

Gail Patricelli	Assistant Professor Section of Evolution and Ecology	GPatricelli@ucdavis.edu
Dr. Patricelli's reserach interests include assessing the ecological effects of anthropocentric noise on avian populations. Her past work includes examining whether road-associated noise is contributing to the declines in sage-grouse populations by assessing the impact of energy extraction and road noise on acoustic communication and reproduction in greater sage-grouse in Wyoming (Connelly et al. 2004).

Jay Lund	Professor, Civil and Environmental Engineering	jrlund@ucdavis.edu
Dr. Lund is interested in the application of systems analysis methods to improve the design of infrastructure including road systems from environmental and economic perspectives. He applies ideas and methods from operations research and economics to such problems.

Jeff Loux	Director, Land Use and Natural Resource Program, UC Davis Extension Adjunct Assistant Professor, Landscape Architecture	jdloux@ucdavis.edu
Dr. Loux studies policy strategies for managing stormwater runoff in road design and construction to alleviate non-point source water pollution and flooding.

John Harvey	Associate Professor, Civil& Environmental Engineering Principal Investigator, UC Pavement Research Center	jtharvey@ucdavis.edu
Dr. Harvey is interested in maximizing pavement performance and economic efficiency, while increasing sustainability of pavement operations in terms of materials use. He is also interested in reducing the impact of pavement operations on the environment as well as road users through reductions in travel delay caused by maintenance, rehabilitation and reconstruction.

Mark Marino	Professor, Land Air Water Resources Professor, Civil and Environmental Engineering	mamarino@ucdavis.edu
Dr. Marino uses computer modeling to study pesticide/herbicide transport in surface and subsurface environments. This research is used to inform hydrologic and environmental systems analysis and planning.

Massoud Kayhanian	Associated Director of CEWRE	mdkayhanian@ucdavis.edu
Dr. Kayhanian studies the characteristics of snowmelt run-off in the Tahoe basin and investigates of how best to treat this runoff to minimize chemical transport into the lake (Kayhanian, et al. 2004).

Michael J. Kleeman	Associate Professor, Civil & Environmental Engineering	mjkleeman@ucdavis.edu
Dr. Kleeman studies urban and regional air quality problems emphasisizing size and composition of atmospheric particles and gas-to-particle conversion processes. His research indicates that airborne particles with diameters less than 2.5 microns cause adverse health effects and contribute to much of the visibility reduction observed in large cities.

Patricia Lyon Mokhtarian	Professor of Civil and Environmental Engineering and Faculty Associate, Institute of Transportation Studies	plmokhtarian@ucdavis.edu
Dr. Mokhtarian is interested in travel behavior and travel trends. Her research provides evidence that drivers enjoy a period of travel time between home and work, showing some positive utility of travel itself, independent of the utility of reaching a destination (Mokhtarian & Salomon 2001).

Peter Moyle	Professor, Department of Wildlife, Fish, and Conservation Biology Center For Watershed Sciences	pbmoyle@ucdavis.edu
Dr. Moyle has studied the impact of roads on Sierra meadow systems and biota; aquatic system change; has shown that density of roads in proximity to streams is linked to watershed degradation (Moyle & Randall 1998). Another study indcates that roads help facilitate the invasion of alien organisms into aquatic systems (Marchetti et al. 2004).

Susan Ustin	Director, WESTGEC Center for Spatial Technology and Remote Sensing (CSTARS) California Space Institute Center of Excellence (CalSpace) Department of Land, Air, Water Resources	slustin@ucdavis.edu
Dr. Ustin uses high performance spectroscopic mapping and modeling techniques to study plant species invasions in aquatic and terrestrial systems (Underwood et al. 2003).

Thomas M. Young	Associate Professor, Civil & Environmental Engineering	tyoung@ucdavis.edu
Dr. Young's research involves analyzing the prevalence of herbicides in highway runoff, their fate and transport, and their ultimate potential toxicity (e.g. Huang et al., 2004). He is also involved in the development of source control strategies for the control of herbicides. This work involves testing new technologies such as a mulch-based treatment system for herbicides.

Walter Boyce	Professor, Pathology, Microbiology, and Immunology Executive Director, Wildlife Health Center	wmboyce@ucdavis.edu
Dr. Boyce works extensively with mountain lions and other widely dispersed animals in California. Recent work includes tracking radio-collared mountain lions in Southern California to identify connections and chokepoints in roadways that facilitate or block lion movement. His research indicates that interstate highways represent significant chokepoints that negatively impact lion populations. Other work involves the study of the effects of off-highway vehicle (OHV) road closures in Anza Borrego Desert State Park. This work indicates that road closures enhance resource protection in terms of effects on streambeds, vegetation, birds, mammals, and amphibians (Ostermann & Boyce 2002).

Wendy K. Silk	Professor, Land, Air, and Water Resources	wksilk@ucdavis.edu
Dr. Silks studies the cycling of two roadside heavy metals, copper and zinc, through a stream-soil-plant ecosystem. Her research indicates that patterns of plant development interact with seasonal precipitation to regulate the sequestration of mineral elements (Boyer & Silk 2004).
