West Sacramento, California

Jamie has over nine years of experience monitoring and analyzing data collected from habitat restoration projects in the California Central Valley. Her skills include spawning and stranding surveys, seining, macroinvertebrate sampling, carcass surveys, rotary screw and fyke trap operation, fish and macroinvertebrate identification, and trace element/stable isotope microchemistry analysis. In addition to monitoring restoration projects, Jamie plays an important role in data visualization, spatial and statistical data analysis, and report writing. Her current research specializes in using microchemistry to explore life history diversity and early development of white sturgeon in the Sacramento/San Joaquin rivers in California.
