Macy is a Ph.D. student in Dr. Shannon Manning’s lab in the Microbiology and Molecular Genetics (MMG) department. Her projects include identifying novel mechanisms of pathogenesis by group B Streptococcus (GBS) and characterizing probiotic effects of Lactobacillus. She is currently investigating the effects of Lactobacillus membrane vesicles on GBS growth and survival. Macy earned her B.S. in Microbiology at the University of Wisconsin – Madison where she worked as an undergraduate research assistant in Dr. Tom Friedrich’s lab studying the within-host evolution of influenza virus. During her summer breaks as an undergrad, she also performed research in Dr. Chris Waters’ lab at MSU investigating second messenger signaling pathways in Vibrio cholerae. Apart from research, Macy is passionate about empowering women in science and is actively involved in the Graduate Women in Science (GWIS) student organization where she serves as the Treasurer of the Mid-Michigan chapter. Macy also serves as the MMG graduate student representative on the Student Advisory Council for the College of Natural Sciences. In her free time, Macy loves to snuggle with her cat, Bubba, and watch MSU basketball!
