Dr. Dennis’ lab focuses on the concept of emotion regulation to better understand how emotions promote competence or in some cases create vulnerability for psychopathology, particularly anxiety and mood disorders. Her work integrates the use of neurophysiological (EEG/ERPs), physiological (EMG/HR) and behavioral assessment tools to identify neurocognitive mechanisms underlying affective psychopathology, anxious stress reactivity, and its remediation. Topics of interest include: (1) Biomarkers for emotion regulation and anxiety-related threat biases; (2) neurocognitive processes underlying the remediation of attention dysfunction and stress reactivity in anxiety; (3) emotion-cognition integration; and (4) the use of novel delivery systems, such as mobile applications, for mental health and stress reduction treatments and the neural mechanisms underlying treatment efficacy.
