Dr. Grady’s research uses functional and structural neuroimaging techniques to study cognitive aging. The work aims to determine how the functional connectivity of various brain networks mediates cognition and how this connectivity is modified by age. Her recent work has shown that age differences in connectivity of the fronto-parietal control network influence connectivity in other networks, and that stronger inter-network connectivity of this network during encoding is beneficial for memory performance in older adults. Other work has shown lifespan differences in the relation between brain network connectivity and cognitive control, and that these differences are relevant for adaptive function in everyday life. Additional research projects involve assessing brain signal variability in relation to aging and cognitive performance, and using predictive modeling to identify patterns of brain activity linked to successful vs. unsuccessful memory retrieval in young and older adults.
