Aaron Galloway; PhD, Associate Professor, OIMB (PI)


Aaron works on aquatic trophic ecology, with a focus on fatty acids as biomarkers for inferring food web relationships and tracking across-system energy subsidies. Aaron completed his Ph.D. in 2013 at the University of Washington School of Aquatic and Fishery Sciencesworking at Friday Harbor Laboratories. Aaron is currently an Associate Professor at the University of Oregon Institute of Marine Biology.

Jessie Masterman; PhD Candidate, OIMB


Jessie is interested in studying marine trophic ecology through a chemistry lens, with a particular focus on gelatinous organisms. Jessie received B.S. degrees in geology and chemistry from the University of Wisconsin in 2010 and a M.S. degree in marine science from KAUST in Saudi Arabia in 2012, under Dr. Michael Berumen. After a stint in industry, Jessie has returned to marine science at OIMB, where she is working on the trophic ecology of gelatinous zooplankton.

Elizabeth Diehl, 1st Year PhD Student, OIMB


Elizabeth received her master’s degree in 2022 from Western Washington University, working on the recovery of threatened pinto abalone in the Salish Sea. Her research was aimed at determining the best water chemistry conditions to outplant post-set pinto abalones into. For her PhD, Elizabeth is planning to use fatty acids as trophic biomarkers to study European green crab trophic ecology and the consequences of this species invasion on Oregon's fisheries. Elizabeth's ResearchGate.


Rhodalyn Tetteh; PhD Candidate, ESSP, OIMB


Rhodalyn is interested in marine trophic ecology from a Political Ecology perspective, exploring the social-political factors that contribute to the production and use of plastics in society, and how they contribute to marine microplastic pollution. Rhodalyn received a BSc degree in Environmental Science (2015), and an MA in Environmental Management and Policy (2017) both from the University of Cape Coast (UCC), Ghana. She is co-supervised in her Ph.D. by Dr. Peter Walker and Dr. Galloway. She can be reached by email.

Emily Vidusic, Research Technician, OIMB


Emily is interested in quantitative kelp forest ecology. She is researching kelp forest trophic interactions by using novel applications of statistical analyses and multivariate model building. She received her B.S. in Marine Science and Statistics minor in 2023 from California State University, Monterey Bay, where she studied rocky intertidal ecology for 2 years. As a research technician, Emily is currently focused on the Kelp Forest Snapshot Assessment project with the Oregon Kelp Alliance (ORKA).
