Cassie Nelson, Ph.D.

Cassie pic for lab websiteCassie 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 the sequestration of metals by the immune system affects the physiology and interactions between Pseudomonas aeruginosa and Staphylococcus aureus.
