Current lab members and volunteers
Tim Davidson (PI)
Dr. Davidson studies marine ecology, conservation biology, and human impacts in the marine and aquatic environment. He received his BS in Environmental Science at Oregon State University, MS in Biology from the Oregon Institute of Marine Biology, and PhD in Environmental Sciences and Resources at Portland State University. Davidson also completed post-docs at the Smithsonian Tropical Research Institute in Panama and University of Hawaiʻi at Mānoa. When he is not exploring wetlands, reefs, or the intertidal, he enjoys surfing, travelling, and practicing Judo as an assistant instructor at the Sacramento State Judo Club.
Sarah Albright (MS student)
Sarah studies marine ecology, phycology, and invasive species. She received her B.S. (Honors) in Marine Biology from the University of Hawaiʻi at Mānoa, where she studied the nutrient uptake and partitioning of a green invasive alga on Oʻahu, Avrainvillea lacerata. Sarah also worked for NOAA's National Marine Sanctuaries, Papahānaumokuākea Marine National Monument as a scientific communications intern during her time in Hawaiʻi. Her Master’s thesis investigates the vegetative fragmentation and dispersal of algae in the San Francisco Bay. When she’s not working or adventuring along shorelines of the Pacific, she is doing science outreach and education, camping in the Sierra Nevada mountains, or writing fantasy novels and leading games of Dungeons and Dragons with her friends.​ 
Jessica Nichols (MS student)
​Jessica is interested in conservation biology, wildlife conservation, and fisheries management. She completed her BS in Biology from California State University San Marcos.  Nichols is studying how wood-boring ecosystem engineers alter wood habitat structure and invertebrate community composition in the Florida mangroves.  She currently works full time as an Environmental Scientists at the California Department of Fish and Wildlife.

Rebecca Pilakowksi (New MS student)

​
​Cassandra Rodriguez (undergraduate researcher)
Cass is an undergraduate in her final semester at CSUS and is primarily interested in Conservation Biology and Wildlife Conservation. Her interests are in invasive species impacts on native ecosystems, habitat fragmentation, and biodiversity. She is a mother and an 8-year veteran with the United States Air Force, where she severed as an Aerospace Medical Service Technician/EMT. She is currently researching and conducting a meta-analysis as an undergraduate researcher on the feeding and burrowing effects of the globally invasive species, Myocastor coypus (nutria). She received research funding through the CSUS COAST program and SEE program at CSUS.
Ethan Roberts (former undergraduate researcher & current volunteer)
Ethan is a recent graduate of our evolution ecology and conservation program (BS, 2020) and is now finishing up his project while also working full time for the state! He has spent most of his undergraduate career working with Dr. Davidson to investigate how burrows formed by an invasive ecosystem engineer affect intertidal invertebrate communities in the San Francisco Bay. He is currently preparing his work for publication in a scientific journal. While much of his time is spent between school and research, Ethan moonlights as a science illustrator, portrait artist, jazz pianist, and piano instructor. Ethan received several research awards at CSUS including COAST awards and an NSM SURE project award.
