About

Rebecca Case is a microbial ecologist studying the effects of bacterial-algal interactions on the marine sulfur cycle and on climate change more broadly. She received her PhD in microbial ecology in January 2007 from the University of New South Wales, Australia, where she also earned a BA in environmental studies and a BSc in environmental science. Her doctoral work at the university's Centre of Marine Biofouling and Bioinnovation involved isolating the bacterium Ruegeria R11, a novel bacterial pathogen of algae whose virulence is temperature dependent, similar to bacterial-induced bleaching of corals. Her research suggests that algae may be susceptible to similar impacts from rising ocean temperatures due to global warming. As an Environmental Fellow at Harvard, she collaborated with Roberto Kolter of Harvard Medical School to further investigate bacterial-algal interactions and their role in the release of dimethyl sulfide (DMS), a climate-regulating compound produced from algal-derived dimethylsulfoniopropionate (DMSP). DMS plays a significant role in cloud formation, which has a cooling effect on local temperatures. Her work highlights the potential for bacterial-algal interactions to produce a negative feedback mechanism in climate regulation, where increased virulence of bacteria could lead to more DMS release and enhanced cloud formation, thereby contributing to a self-regulating climate process.
