My program of study advocates for an individualized science of cognitive functioning, particularly in populations that are susceptible to cognitive impairment. At the University of Illinois, I have primarily focused on individuals with traumatic brain injury
(TBI) and older adults (65+ years of age). Within this context, my research follows three-interconnected tracks. One aim is to operationalize cognitive constructs with greater specificity at the behavioral level (e.g., breaking down larger constructs into smaller constructs), as well as at the level of brain topography and topology. This research endeavor would serve to improve current neuropsychological assessment measures. A second aim is to identify the scope of brain plasticity in these populations of interest. To this end, my research seeks to identify the specific mechanisms of cognitive functioning that change (a) following a TBI or attributed to the natural aging process, and (b) in response to lifestyle changes and interventions. A third, related aim is to identify individual differences in brain morphology and their association with cognitive abilities and co-occurring biopsychosocial symptoms. Information at this level can inform the development of both personalized as well as manualized interventions that promote cognitive restitution and improve psychosocial functioning.
