Sudeep graduated in 2003 with a Ph.D. in ecology from the University of California- Davis under the guidance of Dr. Charles Goldman. He moved to the Center for Limnology, University of Wisconsin- Madison to conduct a postdoctoral research with Dr. Jake Vander Zanden. 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: Solutions for Sustainability. Since 1997, as participant in the Tahoe-Baikal Institute, a Russian-American exchange program, and later as a graduate student and professor, 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. His scientific efforts have been closely linked to the needs of the management community; guiding some of the recent policies to protect Lake Tahoe. Starting in 2005, Sudeep became the coDirector of the Castle Lake Environmental Research and Education Program. This program supports the longest (>57+ year) running collection of ecological data in North and South America.  In this position, he incorporates place-based learning approaches when training students and post-doctoral researchers from the United States and other countries in limnological field methods and analysis.  In 2012-13, Sudeep served as a Program Director at the U. S. National Science Foundation.  He has received awards for his efforts including: American Fisheries Society’s CA-NV Award of Excellence, the Tahoe-Baikal Institute Alumni of the Year, University of Nevada’s College of Agriculture, Biotechnology, and Natural Resources Teacher of the Year, and his favorite, the Mad Hatter’s Award from the Interdisciplinary Graduate Program in Hydrologic Sciences, which he now serves as an Acting coDirector. He feels like there is much more to give in life, and will continue to work to help his fellow humans and the environment in which they inhabit.  For more information about Dr. Chandra go to http://www.unr.edu/biology/people/sudeep-chandra

Max Mortiz

Max Moritz is a statewide wildfire specialist within UC Cooperative Extension, and he has been faculty at UC Berkeley for the last 13 years.  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 on fire-prone landscapes.  He has used a number of different spatial approaches to quantitative analyses of fire history patterns, stemming from his early work on chaparral shrublands in the Santa Barbara region and spanning to global scales under climate change scenarios.  For more information about Dr. Moritz go to https://nature.berkeley.edu/moritzlab/people/

Ramon Naranjo

Ramon C. Naranjo is a research hydrologist at the U.S Geological Survey with professional experience in fate and transport of nutrients in groundwater and surface water systems.  He has 24 years of experience at federal and state agencies investigating legacy environmental contaminants in soils and groundwater. His field of interests include biogeochemical processes, nutrient cycling and transport.  During the last few years, he has focused on understanding nutrient cycling in hyporheic zones and developing models to describe coupled heat and reactive transport.  The objectives of his research is to understand the linkages between ecosystems and biogeochemical processes at the sediment-water interface. 

Dr. Naranjo has used his field experience to develop, design, and patent a new self-contained distributed temperature probe for use in quantifying groundwater flow rate and direction.  This probe has been useful for long-term monitoring that has contributed to understanding and quantifying time-variable processes such as flow rates and describing subsurface heterogeneity using advanced model calibration techniques.  Recent research has demonstrated the utility of the probe in Lake Tahoe nearshore environments to characterize nutrient transformations and groundwater discharge.  For more information about Dr. Naranjo go to https://www.usgs.gov/staff-profiles/ramon-c-naranjo/

My-Linh Nguyen

She currently serves as the Bureau Chief for Safe Drinking Water at the Nevada Division of Environmental Protection (NDEP), under the Department of Conservation and Natural Resources (DCNR). My-Linh oversees and participates in numerous environmental programs, which serve to protect public health through regulatory oversight of, and providing technical assistance to, public water systems in Nevada to ensure provision of safe and reliable drinking water. 

 

My-Linh Nguyen’s previous research includes examining the fate and transport of organic carbon and other nutrients, reducing taste and odor and assessing other algae-related water quality in arid region watersheds and reservoirs. Prior to joining NDEP in 2006, she was a project manager at the Water Research Foundation in Denver, Colorado.  She worked with utility managers, regulators, engineers, and scientists to develop, prioritize and manage research in drinking water treatment and distribution system water quality.  At NDEP, My-Linh works collaboratively with stakeholders to develop and implement programs and tools to protect drinking water supplies from known and potential contamination sources, including the development of a GIS-based groundwater nitrate assessment tool.

Steve Sadro

Steven Sadro is an assistant professor in the Department of Environmental Science and Policy, at the University of California, Davis.  Hi work focuses on how biological, physical, and chemical factors interact to regulate aquatic systems. He completed his Ph.D. in limnology at UC Santa Barbara before joining the faculty at UC Davis in 2016.

Limnology is the study of inland waters. As water flows across the landscape, a wide range of processes, both natural and derived from human activities, affect aquatic ecosystems.  Dr. Sadro studies the impact of these processes on the structure and function of aquatic ecosystems. In particular, he is interested in how changes in climate are affecting aquatic ecosystems. He studies terrestrial-aquatic interactions, the flow, cycling, and transformation of carbon and nutrients in aquatic ecosystems, and food-web dynamics.

 

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. Much of his research is conducted in the Sierra Nevada of California, where steep mountain gradients provide a natural laboratory to study these dynamics. Ultimately, his research seeks to inform management policies to chart a path toward the continued health and conservation of our aquatic ecosystems.
