Dr. Strickland’s research seeks to better characterize traumatic brain injury, dementia, and related neurobehavioral disorders across the life span.

Dr. Strickland utilizes multi-project investigations that employ brain imaging, neuropsychological, and other neurobehavioral assessments to pursue two overarching research themes:

• the understanding of potential differential expression of neurobehavioral disorders among underserved populations across the life span.

• the identification of effective assessment and diagnosis, and potentially promising treatment interventions to be explored in future clinical service and research.

An underlying focus of his work is the development of a research program consisting of experienced and committed professionals conducting innovative clinical neuroscience investigations that attract scientists from regional, national, and international communities.

He has been the principal investigator of a number of National Institute of Health supported research investigations, and has managed a large number of other projects primarily related to clinical neuroscience. He is the author of numerous research articles and has presented nationally and internationally.
