Jennifer Biddle

Associate Professor

My research is focused on microorganisms in the environment, and understanding what they do and where they are. Environments we examine include local marine sediments, the deep biosphere and microbialites. We examine microbial diversity at all levels, including bacteria, archaea and fungi. We employ next generation, high throughput sequencing techniques and bioinformatics, cultivation and geochemistry techniques in our studies.
