Alexandra Nicole Trelle

I completed my undergraduate degree at the University of Toronto, and my PhD at the University of Cambridge. My work explores the neural mechanisms supporting episodic memory, and how these are affected by aging and Alzheimer's disease. I am currently leading the Stanford Aging and Memory Study, a large-scale longitudinal project examining individual differences in episodic memory in older adults. My research combines structural and functional MRI, PET imaging, and analysis of molecular and genetic risk factors for Alzheimer's disease.
