Dr. Cassandra (Cassie) Nelson began working as a postdoctoral researcher in the OS Lab in October. Cassie completed her doctoral training in the Biological Sciences Department at the University of Maryland, Baltimore County in the fall of 2017. Using a combination of transcriptomics, microbial genetics and physiology, her dissertation work determined the physiological roles of the glycoside hydrolase family 3 enzymes in the bacterium Cellvibrio japonicus. She is currently studying how iron regulation affects the physiology and interactions between Pseudomonas aeruginosa and Staphylococcus aureus. Welcome Cassie to the OS Lab!!
