Dr. Geoffrey Schladow holds B. Eng. and Ph.D. degrees in civil engineering from the University of Western Australia, and an M. Eng. in hydraulic engineering from the University of California at Berkeley. For over thirty years his research has focused on the interactions between the complex fluid motions found in nature and their impacts on water quality, ecosystem health and watershed processes. Dr. Schladow is a Professor of water resources and environmental engineering at the University of California, Davis, and is the founding director of the UC Davis Tahoe Environmental Research Center (TERC).
Sudeep graduated in 2003 with a Ph.D. in ecology from the University of California- Davis under the guidance of Dr. Charles Goldman. Currently, Sudeep is an Associate Professor of Limnology and Conservation Ecology at the University of Nevada, Reno (USA); he serves as Director of the University’s new initiative the Global Water Center. Sudeep’s research has focused on quantifying the ecological changes in Lake Tahoe from the introduction of species, the loss of native biodiversity and its implications for altering nutrient dynamics and clarity in the lake.
Dr. Adrian Harpold is a Assistant Professor in the Department of Natural Resources and Environmental Science at the University of Nevada, Reno. His current research focus is on understanding changing mountain hydrology as a consequence of climate and land cover change. He works actively in the central Sierra Nevada, with field sites of the West Shore of Lake Tahoe and Sagehen Creek Watershed that are used to study ecohydrology and forest management.
Dr. Heyvaert is an Associate Research Professor and limnologist at the Desert Research Institute with professional experience in a variety of aquatic ecosystems. His fields of interest include biogeochemistry, watershed management and paleolimnology. He has worked for over twenty-five years on water quality issues in the Lake Tahoe Basin, with an applied research focus on effective design of stormwater monitoring systems and performance evaluation of Best Management Practices (BMPs).
Pat Manley is the Research Program Manager, Conservation of Biodiversity Program with the Pacific Southwest Research Station, US Forest Service, Department of Agriculture. She has a Ph.D. from UC Berkeley in Wildland Resource Science, with an emphasis on biological diversity and vertebrate community ecology. She has worked for the National Forest System for nearly 15 years in various positions throughout the Pacific Southwest Region.
John M. Melack is a Professor in the Bren School of Environmental Science and Management and Department of Ecology, Evolution and Marine Biology at the University of California, Santa Barbara. Melack's research has emphasized ecological processes in lakes, wetlands and streams, and hydrological and biogeochemical aspects of catchments. His studies of the saline Mono Lake and high-elevation lakes in the Sierra Nevada have continued for over 30 years, and he is involved in the second decade of an LTER examining linkages among coastal watersheds, near-shore kelp ecosystems and offshore waters in Santa Barbara Channel.
Max has been a statewide wildfire specialist within UC Cooperative Extension since 2004 and is also now an adjunct professor at the Bren School of Environmental Science & Management at the University of California, Santa Barbara. Much of his research is focused on understanding the dynamics of fire regimes at relatively broad scales and applying this information to planning and management of fire-prone landscapes. He has used a number of different spatial approaches to quantitative analyses of fire history patterns that stems from his early work on chaparral shrublands in the Santa Barbara region.
Steven Sadro is an assistant professor in the Department of Environmental Science and Policy, at the University of California, Davis. His work focuses on how biological, physical, and chemical factors interact to regulate aquatic systems. Dr. Sadro combines the use of long-term watershed studies with experimental manipulations and comparative analyses to understand ecological processes in habitats ranging from alpine and arctic lakes, to coastal streams and estuaries.
Adam Watts is Associate Research Professor of Fire Ecology and Unmanned Systems at the Desert Research Institute, where he also serves as UAS Liaison and deputy director of the Climate, Ecosystems, Fire, and Atmosphere Program and the Wildland Fire Science Center. His areas of research include fires in wetlands; ecological restoration; and the development of new tools and technology to serve the needs of fire managers and researchers. He serves on the Board of Directors of the Association for Fire Ecology, and as the liaison between Boards of Directors of the Association for Fire Ecology and the International Association of Wildland Fire.
Josh Wilson is the Research Program Manager for Fire and Fuels, and Urban Ecosystems and Social Dynamics with the Pacific Southwest Research Station, US Forest Service, Department of Agriculture. Josh began his Forest Service Career as a Resource Economist for Ecosystem Management Coordination in Fort Collins, CO in 2006 and has worked on a variety of natural resource projects across several Forest Service Regions before transitioning to the Ecosystem Staff Officer of the Shasta-Trinity National Forest and eventually the Executive Officer of TEAMS Enterprise where he led a multitude of collaborative efforts across the country in support of natural resource conservation. Josh holds a BS in Managerial Economics from the University of California, Davis and an MS in Agricultural and Resource Economics from Colorado State University where he has also served as an instructor of Agricultural Marketing.
Paul Work is a Professional Engineer with ACOPNE board certification in coastal engineering and serves as the Program Chief for Estuarine Hydrodynamics and Sediment Transport at the USGS California Water Science Center in Sacramento, California. Dr. Work joined USGS in 2013 after 20 years as a faculty member in civil and environmental engineering programs at Georgia Tech and Clemson University. He received B.S. and M.S. degrees in civil engineering from the University of California - Berkeley and a Ph.D. in Coastal and Oceanographic Engineering from the University of Florida.
As part of the Tahoe Science Advisory Council's MOU and to ensure proper representation of both California and Nevada, the Council include non-voting state advisors appointed by the Secretary of the California Natural Resources Agency and by the Director of the Nevada Department of Conservation and Natural Resources.
