Carla Guarraia

Carla is the chair of the Upper School science department. She is an advisor to the Beekeeping Club, the International Student-led Arctic Monitoring and Research (ISAMR) program, and the Hiking and Camping Club, and develops Wellness programming.

After earning her Ph.D. in molecular biology and conducting research in chemical and biological engineering, Carla did a brief stint in industry studying nanoparticles for drug delivery. She then turned to teaching, following in her husband’s footsteps, and worked at St. Paul’s School for Girls. After visiting a beekeeping club event at Park, Carla decided she wanted to work here. “Now, I’m the best version of myself, doing research and developing programs that I believe in, supporting students and seeing how their unique experiences can lead to innovative changes that make our world a better place.”

Carla loves working on her mini-farm raising chickens, turkeys, bees and composting to restore damaged soils, but admits that she’s “not so good at raising vegetables.” She also likes more traditional activities, including watching Netflix, doing crafts with friends, and reading middle school fiction.

Carla has a B.S. in Biology/Chemistry Interdisciplinary Studies from Loyola University in Maryland, and a Ph.D. in Molecular and Cellular Biology from the University of Maryland, Baltimore County. She was a Postdoctoral Research Associate in Chemical and Biochemical Engineering at University of Maryland Baltimore County. She is the parent of a Park School student in the Class of 2028.
