Research Interests

     Broadly, I am interested in the neural mechanisms underlying decline in specific cognitive functions in normal and pathological aging. I am also interested in the effectiveness of interventions aimed at ameliorating age-related cognitive deficits. I address these questions using a variety of approaches including fMRI, network analysis and machine learning.


Commitment to Diversity and Inclusion

     I am committed to working toward an inclusive work environment where everyone - including people from racial and ethnic minority groups - is treated with dignity and respect.


     Outside of the lab, I enjoy engaging in regular physical activity.
