    Current Research and Scholarly InterestsAs a postdoctoral fellow in Dr. Erin Gibson’s lab, I am integrating my expertise in molecular signaling and systems neuroscience to study the role of OPCs in sleep. My interest in sleep has been further reinforced by observing the dramatic shifts in sleep architecture across developmental stages as a new parent, highlighting the necessity of sleep for neural refinement. My current research uses in vivo calcium imaging and closed-loop optogenetics to determine how OPC-neuron communication coordinates hippocampal sharp-wave ripples. By characterizing how aging blunts OPC responsiveness to sleep, I aim to identify novel strategies to preserve memory and promote healthy cognitive aging.

    Carolyn Turcotte

    Postdoctoral Scholar, Developmental Biology

    BioCarolyn Turcotte is a postdoctoral fellow in the Villeneuve lab that studies meiotic homolog pairing using an interspecies hybrid model system. She earned her PhD in Genetics and Molecular Biology at the University of North Carolina at Chapel Hill, where she worked in Jeff Sekelsky's lab and studied spontaneous meiotic nondisjunction in Drosophila.
