is the Chief of the Aquatic Ecology Section. He was previously an Environmental Scientist and has worked with
the Aquatic Ecology Section since June 2009. He has a Bachelor of Science in Zoology and conservation from
the University of Wisconsin – Madison (2003) and a Master of Science in Ecology from the University of
California – Davis (2007). Brian’s responsibilities include planning and conducting IEP Pelagic Organism
Decline (POD) special studies. Current projects include an analysis of predators of larval delta smelt
using genetic techniques, and examining historical beach seine data throughout the Bay-Delta system for
patterns in fish community composition.
is an Environmental Scientist and has worked with the Aquatic Ecology Section since January 2011. He previously worked in North Central Region Office’s Water Quality Evaluation Section, where he coordinated with USGS in 2007 on the establishment of a continuous and real-time turbidity monitoring effort in the Central Sacramento-San Joaquin Delta. He is now co-lead on the interdisciplinary monitoring effort in the Yolo Bypass for the collection of baseline data on: juvenile and adult fish, lower trophic levels (phytoplankton, zooplankton and aquatic insects), hydrology and physical conditions. In addition he works with other section members on special studies related to fisheries and general aquatic ecology in the Sacramento-San Joaquin Delta. He received a Bachelor of Arts in Environmental Studies from California State University Sacramento.
is a Environmental Scientist in the Aquatic Ecology Section. He assists with field and office components of Yolo Bypass research on distribution, migration, and abundance of the fish assemblages. He also works with Jared Frantzich on the Large Mouth Bass in the Yolo Bypass. Naoaki received his degree in Biological Sciences from University of California, Davis.
is an environmental scientist in the Aquatic Ecology Section. She received a Bachelor of Science in Biology at U.C. San Diego, and a Master of Science in Marine, Estuarine and Environmental Science at the University of Maryland. Prior to joining the section in February 2012, Lynn worked on estuarine invasion policy and research with the California State Lands Commission and the Smithsonian Environmental Research Center, and on the biogeographic characterization of marine protected areas with the National Oceanic and Atmospheric Administration. Currently, she is examining factors that influence the residence time, emigration, and growth of juvenile Chinook salmon in the Yolo Bypass through the analysis of long-term monitoring datasets. Lynn also provides support for the section's other studies on the aquatic ecology of the Sacramento-San Joaquin Delta.
Brian Mahardja is an Environmental Scientist in the Aquatic Ecology Section. He received his Bachelor of Science degree in Genetics (2009) and Master of Science degree in Ecology (2013) from the University of California – Davis. Prior to joining the Aquatic Ecology Section in 2014, he was the lead on genetic contract and data management for the California Department of Fish and Wildlife’s San Joaquin River Restoration Program. He is currently involved in a study on the distribution and life history of inland silverside (Menidia beryllina) within the Sacramento-San Joaquin Delta. Brian also assists other studies within the section such as the juvenile Chinook salmon predation study and the Yolo Bypass fish monitoring program.
Pascale Goertler is an Environmental Scientist in the Aquatic Ecology Section. She received her Bachelor of Science degree in Environmental Studies (2008) from University of California, Santa Barbara and her Master of Science degree in Aquatic and Fishery Sciences (2014) from the University of Washington, Seattle. Before joining DWR in 2014, Pascale worked for the National Marine Fisheries Service, Southwest Fisheries Science Center and with the Pacific States Marine Fisheries Commission. Her research interests are wetland habitat use and life history diversity of juvenile anadromous fish species in the Sacramento-San Joaquin Delta. She also assists in the section’s other field studies and analysis of long-term monitoring datasets.
is a Fish and Wildlife scientific aide in the Aquatic Ecology Section. She received a Bachelor of Science degree in Evolution, Ecology, and Biodiversity with an emphasis in Wildlife, Fisheries, and Conservation Biology at U.C. Davis (2013). Before joining the section she assisted in invertebrate identification at the Center for Watershed Sciences in Davis, aided in the juvenile salmon-rice field project out at Knaggs Ranch, and volunteered as a crew member for The Moyle Lab’s various studies out at Suisun Marsh. She is currently involved in Yolo Bypass monitoring efforts and other special studies.
is a Fish and Wildlife Scientific Aid in the Aquatic Ecology Section. She received a Bachelor of Science degree in Environmental Science and Management from U.C. Davis in 2013. Before joining the section Mollie worked as a student assistant and later as a Junior Specialist at the UC Davis Center for Watershed Sciences. She currently assists in monitoring efforts on the Yolo Bypass.
