Rachel is a microbial oceanographer who investigates the microbial communities in the open ocean at the Bermuda Atlantic Time-Series Study (BATS) site using a variety of molecular techniques. She is currently investigating how the microbial community adapts to changing oxygen levels within the twilight zone of the Atlantic Ocean. Most recently, Rachel joined BIOS-SCOPE, an international research collaboration that utilizes a broad suite of genomic, ecological, oceanographic and biogeochemical approaches to evaluate microbial process, structure, and function on various scales.
Rachel received her MSc in aquatic resource management from King’s College in London, England. Her degree work included a research project at BIOS, where she previously participated in the Bermuda Program. After graduation, she joined the BIOS staff working as a research technician in the lab of Dennis Hansell investigating dissolved organic matter and the oceanic carbon cycle in the Antarctic, North Atlantic, Arabian Sea, and Pacific Ocean. She presently runs the Microbial Ecology Laboratory and the Microscopy and Image Analysis Facility at BIOS.
Microbial communities within oxygen minimum zones, the open ocean and Bermuda’s inshore waters; microbial response to ocean acidification and anoxia; coral-microbe interactions, including how corals influence the microbial community within the surrounding water.
