Alexandra Trelle, PhD

Research Associate

I received my bachelor's degree from the University of Toronto, where I developed an interest in the effects of aging on episodic memory while working with Morris Moscovitch, Lynn Hasher, and Morgan Barense. I continue to investigate the sources of memory decline in old age here in Cambridge, where I recently completed my PhD with Jon Simons in collaboration with Rik Henson. My research uses a combination of behavioural experiments and functional neuroimaging to investigate the relative contributions of representational specificity and controlled retrieval processes to age-related declines in recollection.
