At the Bench

Megan attended Virginia Tech for her undergraduate studies, receiving a B.S. in Biomedical Biological Sciences as well as a B.S. in Microbiology in 2024. There she studied all things type IV pilus, a prominent virulence factor in many Gram-negative pathogens, in the lab of Dr. Zhaomin Yang. She identified conserved regions of the ATPase, PilB, as potential binding sites of inhibitors, helped develop a phage-based high-throughput screening technique for identifying type IV pilus inhibitors, and discovered that surface hydrophilicity impacts twitching motility in vitro. Wanting to step outside her comfort zone, Megan moved across the country to UC San Diego to pursue translational research in the Nizet Lab, as a Biomedical Sciences Ph.D. student. Currently, Megan evaluates a nanoparticle vaccine against multidrug resistant Escherichia coli with Assistant Project Scientist, Elisabet Bjanes. Additionally, she is identifying the effects that biomimetic platelet nanoparticles, used as a biotherapeutic for Gram-positive sepsis, have on innate immunity.

Outside of Lab

When she's not in lab, you can usually find Megan at home curled up with her cat, Arthur, while crocheting, reading, or puzzling. If she's not at home, she's on the soccer field saving goals and being the team cheerleader. If you ask Megan her hobbies on any given day, she is always trying something new!
