Research

David’s research has examined the cognitive and neural systems that support memory and attention control in young and old healthy individuals as well as persons suffering from mental illness and traumatic brain injury. David’s research is focused on the cognitive neuroscience of mental processes. He has examined the neural structures and computational algorithms that contribute to non-declarative memory, associative memory, metamemory and attention/cognitive control with a range of methodological tools – lesion studies and functional brain imaging (fMRI and MEG/EEG). His most recent work has focused on examining relationships between sleep, emotional regulation and cognition in normal and elderly populations as well as in individuals who experienced neurotrauma. This includes both laboratory sleep studies as well as the use of field monitoring methods for generating sleep/activity rhythms. His lab was one of 3 original sites involved in a national multisite study of traumatic brain injury – TRACK TBI, that has been continuously funded since 2008 and now grown to more than 18 sites.
