Caroline B. Palavicino-Maggio, Ph.D.

Project Title: Unraveling the neural basis of female aggression and dementia-related aggression: a systems biology approach
Institution: Harvard Medical School
Funding NIH Institute/Center: National Institute of General Medical Sciences
Grant ID: K99GM141449
MOSAIC Scientific Society: ASCB

Caroline Palavicino-Maggio grew up in Washington Heights in New York City, and her scientific curiosity began by observing insects – specifically how cockroaches lived in social groups and why they were most active at night. As she grew older these interests remained prominent, and ultimately matured into a deep-rooted curiosity for understanding the neural circuits that mediate complex behaviors. At 13 years old, she experienced a life-altering event when her sister committed suicide. She began to seek out an explanation for this apparently inexplicable event, which focused her scientific interest in studying neural circuits of human behaviors, specifically to understand what happens in the brain during these acts of self-aggression. She received her B.S. degree in Behavioral Neuroscience from Rider College, Lawrenceville, NJ and her PhD in Neuropharmacology and Neurophysiology from Rutgers University, at New Jersey Medical School as an Alfred P. Sloan Scholar. Her current research focuses on understanding the neural basis of female aggression and its relevance in psychiatric and neurodegenerative diseases. She has been consistently involved in activities to promote diversity in many K-12, undergraduate, and graduate pipeline outreach programs. Her latest project includes the creation of a Mini-PhD program, whereby middle and high school students from underserved communities in the local Boston area are involved in completing independent science projects and publishing their results in a peer-reviewed journal. She also currently serves on various diversity committees at Harvard Medical School and plans to continue promoting diversity in the sciences as a future independent investigator.
