Gast, Rebecca Associate Scientist, Biology


My research has the overall theme of molecular protistan ecology. The main focus of my work includes analyses of the genetic diversity, detection, distribution and abundances of protists (algae and protozoa) in the marine environment. Currently my projects in this area include ones examining protistan and bacterial pathogens in the coastal marine environment, and protistan diversity in the extreme environments of the Antarctic and the Arctic. These polar studies have recently led to a project investigating tubulin protein adaptations associated with psychrophilic functions to better understand how organisms have evolved to operate in the extreme cold. I also pursue research projects on the photosymbiotic associations in foraminifera and radiolaria, including the natural distribution of free-living symbionts and algal gene expression in the symbiotic state.
