Graduate Student Excellence-in-Research Award 2017
Hannah Bullock, a recent doctoral graduate in microbiology, is recognized for the new insights her research has provided into a major pathway of the ocean sulfur cycle. Her work focuses on the metabolism by marine bacteria of an organosulfur compound named dimethylsulfoniopropionate that is a major source of the atmospheric sulfur that facilitates cloud formation. Her research offers new insights into the biochemical regulation of the pathway as well as its evolutionary history. Bullock has also made essential contributions to three other papers, has distinguished herself as a contributor to scientific work outside her own field, and has been an active collaborator with fellow graduate students and a mentor for undergraduate students in the laboratory. She currently is a postdoctoral associate in microbiology at UGA.
