I am interested in the biobehavioral features of emotion regulation in individuals with chronic pain. A major focus of my research to date has centered on the measurement and analysis of dynamic measures of pain and emotion captured in the course of daily life. We employ laboratory tools, such as quantitative sensory testing and sleep deprivation, to investigate the reproducibility of information gathered in daily life. We are currently developing behavioral (e.g., sleep behaviors) and neurobiological (e.g., dopaminergic neurotransmission) models to understand the influence of positive emotion and reward processing on pain sensitivity and coping with chronic pain. In the long term, our aim is to improve treatment options for individuals with chronic pain, including those with comorbid substance use disorders.
