We each spend about a third of our lives sleeping. Why? As a cognitive neuroscientist, Dr. Erin Wamsley studies this relatively uncharted territory, exploring the function of sleep, the brain basis of dreaming, and the role of resting states in memory consolidation more broadly.
Dr. Wamsley began her academic career as a liberal arts student at Guilford College in North Carolina, where she double-majored in psychology and philosophy. She then went on to complete her doctoral studies at the City University of New York, where she spent long hours working in a sleep lab in Harlem, teaching undergraduates at City College, and failing to get enough sleep herself. After obtaining her Ph.D. in 2007, Dr. Wamsley began a postdoctoral fellowship in the Division of Sleep Medicine at Harvard Medical School, where she was later promoted to instructor of psychiatry. During this time, Dr. Wamsley primarily focused on her research, authoring more than 30 research articles, reviews, and book chapters.
Joining the Psychology department and Neuroscience major at Furman in 2014, Dr. Wamsley is returning to her liberal arts roots and a love of undergraduate education. She looks forward to working with students in the classroom, in the laboratory, and everywhere in between. She also keeps busy with a husband, a toddler, and two cats (named after features of the sleep EEG: “Ripple” and “Spindle”).
Dr. Wamsley is always looking for motivated students to work with her on research in the The Furman Sleep Lab.

Dr. Wamsley's research concerns the function of "offline" states of sleep and rest, and especially their role in the consolidation of memory. In her laboratory, research questions include:
- What happens to a memory after initial learning? One arm of Dr. Wamsley's research explores the hypothesis that recent memories are actively processed in the sleeping brain, as new learning is "consolidated" over time.
- What is happening in the brain during sleep? To better understand the brain dynamics that support memory consolidation, Dr. Wamsley's research takes advantage of innovative methods in EEG.
- How does the sleeping brain generate dream experiences? Dr. Wamsley's past research suggests that dreams may result in part from the reactivation of recent memories in the sleeping brain.
