Sarah Burnet (Student Director)

Sarah Burnet is pursuing her Ph.D. at the University of Idaho, where she completed a MS in the spring of 2016. She received a BS from Western Washington University. Her Ph.D. research is focused on internal loading of phosphorus to reservoirs. Specifically, she is interested in understanding the relationships between sediment type, particle size, the availability of iron, and dissolved oxygen in the release of P. This builds on her MS research which focused on measuring the seasonal internal phosphorus load as part of a mass balance for Willow Creek Reservoir in Oregon. Sarah’s previous work experience includes sampling and analysis on all five Great Lakes with Cornell University as well as collecting data and samples after the BP Deepwater Horizon Oil spill. Sarah has been a member of NALMS since 2014.
