Research in the Gratton Lab explores how the human brain flexibly coordinates goal-directed behavior with perception and memory, using advanced neuroimaging techniques. Our work centers on functional Magnetic Resonance Imaging (fMRI), with a particular focus on precision fMRI—an approach that deeply samples individuals to precisely map brain networks and cognitive processes at the individual level. While fMRI is our primary tool, we also incorporate complementary methods such as transcranial magnetic stimulation (TMS) and patient studies.
Recent projects investigate variability in brain networks, the role of control-related regions in the frontal and parietal lobes, and changes in these processes with brain aging.
Our principal investigator is Dr. Caterina Gratton.

Our research focuses on several key areas:
- the organization and function of large-scale brain networks and hub regions,
- top-down control systems that guide flexible behavior based on goals, and
- the development of new methods to measure brain function across individuals, tasks, and time.
We are particularly interested in questions such as:
- What functions do hub regions—those that interact across multiple networks—serve?
- How do networks vary across time, context, and individuals?
- How do brain networks break down, and how do they support complex behavior?
