Peggy Lehman is a Staff Environmental Scientist in the Special Studies Research Section. She received her Ph.D. in Ecology from the University of California at Davis.

Her current research focuses on the growth and toxicity of the toxic cyanobacterium Microcystis aeruginosa in the Delta, high frequency phytoplankton and zooplankton distributions in the Delta using flowCAM technology and wetland production.

Previous research includes quantifying material flux in freshwater tidal wetlands, causes of oxygen depletion in the San Joaquin River and the influence of climatic factors on affect phytoplankton species composition and food web dynamics.

Cynthia Le Doux-Bloom is a Staff Environmental Scientist. She holds a Ph.D. in the Animal Biology from UC Davis, M.S. degree at San Jose State University (Moss Landing Marine Laboratories), and a B.S. in Marine Biology from UC Santa Cruz.

Cynthia has over 20 years of experience leading complex fishery focused scientific investigation in the Ocean, SF Estuary, and coastal watersheds. Before joining DWR, she worked at the Dept. of Fish & Game, the Monterey Bay Aquarium, and the Monterey Bay Aquarium Research Institute. Her research includes investigating the migration ecology of wild anadromous fishes, specifically juvenile salmonids and sub-adult striped bass.

She designs and implements large scale acoustic telemetry studies to investigate fish distribution, habitat use, and movement patterns. Special studies have included surgical techniques to implant transmitters, behavior around non-physical barriers, predator-prey habitat overlap, and defining habitat preferences across spatiotemporal contexts.
