Matt Dixon

How do we effectively focus on important events in the external environment  or an internal train of thought?  I am interested in delineating the brain network dynamics that govern attention, with an emphasis on the default network, dorsal attention network, and frontoparietal control network.  My research employs graph theoretical analyses in conjunction with resting-state and task-based functional connectivity data to examine how brain network organization changes across different contexts.
