Eleanor (Ellie) Arrington is a postdoctoral researcher at the University of California, Santa Barbara, supported by a National Science Foundation Postdoctoral Fellowship in Ocean Sciences. She studies hydrocarbon metabolism in marine microbes using metagenomics, exploring how these microbial communities evolve and function in both the surface ocean and the deep sea. Her research focuses on microbial life at deep-sea natural oil seeps, with a growing interest in symbiotic relationships between hydrocarbon-degrading bacteria and deep-sea fauna at natural seeps and hydrothermal vent systems. Through her work, Ellie aims to better understand the role of microbial metabolisms in ocean ecosystems and their broader implications for biogeochemical cycling and carbon flow.
