Dr. Vargas will be accepting a new graduate student for Fall 2020. 

My overall research aim is to enhance our understanding of the biopsychosocial factors that contribute to the development and maintenance of both depression and insomnia, with the end goal of identifying clinically useful markers that may inform treatment and prevention efforts. My research broadly investigates the neurobiology of depression and insomnia and aims to evaluate:

(1) the role of the HPA-axis and sleep [disturbance] in the development and maintenance of depression;

(2) the shared psychological and neurobiological concomitants of depression and insomnia and how these may help us understand the pathways by which these disorders develop sequentially and/or simultaneously; and

(3) the cognitive biases or neuropsychological deficits that are associated with increased risk for both disorders.
