Sairah Malkin

Sairah Malkin is an aquatic ecologist, interested in the interactions between microbial ecology and geochemical transformations.

During her PhD, under the direction of Bob Hecky and Stephanie Guildford, Sairah was engaged in investigations of benthic-pelagic coupling in the Laurentian Great Lakes, specifically focussing on the ecology of macroalgae and their interactions with invasive mussels. Most recently, Sairah arrived from Belgium/The Netherlands where she investigated the ecology of newly discovered sulphur oxidizing bacteria with the ability to conduct electricity over centimeter-scale distances, by a process that is yet enigmatic. She recently demonstrated that these unusual bacteria are surprisingly widespread in marine coastal sediments, which could have major implications for surface sediment geochemistry.

Sairah joined the Joye lab in Feb 2014 where she will be investigating the biogeochemistry and microbiology of hydrocarbon degradation in the Gulf of Mexico.
