Research conducted by 2015 PEP Fellow, Rebecca Spencer, on sleep and how it affects learning and memory, is featured in Medical Xpress. "People are talking about sleep more now," Spencer says. "Doctors have realized that they need to ask patients about sleep, but they don't have the answers. So, they send them for a sleep study. Well, everyone has some level of sleep disorder – we just don't know enough about how to delineate them." Spencer says she is currently studying sleep in both preschoolers and the elderly.
