Research in the MINDSET lab is focused on understanding the chronic effects of brain injury and psychological stress on the human brain and health outcomes. We use neuroscience tools such as Magnetic Resonance Imaging (MRI) including structural T1-weighted imaging, diffusion tensor imaging, and fMRI to examine potential links between trauma and neurodegenerative disease. In addition, a primary focus in the lab is to investigate the neural correlates of cognitive processes such as memory and attention, social and emotional processes. We also examine how genetiv and epigenetic factors moderate outcomes after injury and through the aging process. Our research investigates the long-term consequences of injury to the brain, including links to neurodegenerative diseases such as Alzheimer's disease, and interactions with mental health disorders.
