Linnea Bavik, ’17, B.S. mathematics, physics, spends her days studying the social lives of bacteria.
“Bacteria are very social organisms,” Bavik says. “They are constantly signaling to each other to figure out who to help and who to hurt. And they can do some crazy things, evolutionarily, like killing themselves to help the collective.”
While they’re mingling and signaling, bacteria can also share genes in a process called horizontal gene transfer. And genes for antimicrobial resistance get a little extra oomph.
“Oftentimes, horizontally transferred genes are encoded on extra-chromosomal units called plasmids,” Bavik says. “These plasmids can evolve some very interesting strategies, such as offering the host some benefit, such as antimicrobial resistance genes. I’m researching the relationship between plasmids and what environment we expect to see antimicrobial resistance arise.”
Bavik was delighted to find mentors at Western who encouraged her to try difficult classes and projects.
“I wanted to take risks with my education, to try things that may be very difficult for me and at which I might not achieve a high grade on my first try,” she says.
