Each summer, Bryn Mawr provides 35-plus students with 10-week research stipends to conduct independent research under the guidance of Bryn Mawr faculty members in the sciences and mathematics. Below are just a few of the opportunities students had to do research this summer.
Impact of Childhood Adversity
Students working with Assistant Professor of Psychology Cora Mukerji as part of the DEER lab are researching how childhood adversity leads to different developmental outcomes.

Students working with Assistant Professor of Psychology Cora Mukerji as part of the DEER lab are researching how childhood adversity leads to different developmental outcomes. This summer, they’re doing literature searches, practicing collecting electroencephalogram data, and doing individual research projects.
“There are a lot of steps in the research process that I knew of in theory but I’d never done them,” says psychology major Clare Hann ’27. “I learned far more doing the hands-on work than I would have just hearing about it in a classroom. You run into a lot of problems, but eventually you solve them.”
Cellular Security Guards
Bacterial cells, like E. coli, are surrounded by a membrane that acts like a security gate. There are proteins embedded within this membrane that act as security guards to allow different types of molecules to enter or exit the cell. Assistant Professor of Chemistry Ashlee M. Plummer-Medeiros and her Summer Science students use both computational and biochemical studies to understand how membrane proteins work and how they interact with the membrane, or gate, itself. By understanding how these security guards work, scientists can design better antibiotic drugs to target them and the bacteria that they protect.
“In the Plummer Lab, I get to exercise both my ability to plan achievable research goals while also developing technical skills,” says Jenna Mackenroth ’26.

The Memory of a Fly
Assistant Professor Hannah Shoenhard’s lab uses the powerful and precise genetic tools available in the fruit fly to discover the cellular and molecular mechanisms by which sleep facilitates long-term memory consolidation.
The brain is the most energy-hungry organ in the body, burning 20 percent or more of the calories people consume. When we do something that requires extra “brainpower,” like forming a long-term memory, that energy has to come from somewhere—the question is, where? The Shoenhard lab uses fruit flies as a model to investigate how memory-consolidating neurons source their energy at multiple levels: from their own reserves, from other brain cells, and even from the energy reserves of the whole organism.
“In particular, because sleep plays an important role in supporting long-term memory, we’re testing the hypothesis that these memory-supporting energetic processes are more efficient during sleep,” says Assistant Professor of Biology Hannah Shoenhard. “Our work sheds light on the fundamental energy-sourcing mechanisms by which memory functions.”

The Summer Science Research program also includes professional development workshops and a poster session where students present their research to the college community.
