Marissa Maheu, PhD
Marissa Maheu, PhD, is a postdoctoral fellow in the Neurobiology of Fear Laboratory led by Kerry Ressler, MD, PhD and current recipient of a Canadian Institutes of Health Research Fellowship. Following the completion of an Honours BSc at the University of Toronto, Dr. Maheu joined the lab of Naguib Mechawar, PhD, at McGill University to pursue her doctorate in neuroscience. There her work with the McGill Group for Suicide Studies focussed on characterizing deficits in cellular plasticity in brain regions involved in emotional processing and their association with suicide. As a postdoctoral fellow in Dr. Ressler’s lab, Dr. Maheu is investigating cell-type-specific contributions to fear learning. She is particularly interested in hyperplastic interneurons (HINs) in the amygdala, a unique population of neurons that display many of the characteristics of immature cells but whose function remains unknown. Using a range of transgenic and molecular approaches, Dr. Maheu hopes to disentangle the role HINs play in fear and clarify their contribution to amygdala circuit function.
