About Alexandra Peterson
Alexandra received her bachelor’s degree in Biochemistry from Stony Brook University, where she developed her interests in the microbiome, metabolomics, and host-pathogen interactions. She rotated in the Lemos-Abranches lab before joining in 2020 as a Ph.D. student in the University of Florida’s Biomedical Sciences program. She now is doing microbiological research concerning Streptococcus mutans, a bacterial pathogen with a major role in caries (cavity) development. S. mutans competes with the human host for essential nutrients like Zinc, which must be tightly regulated. Because of this, her project focuses on the systems by which S. mutans regulates Zinc homeostasis.
