Research Interests
My work has focused on modeling emotional and personality development across childhood and adolescence. I am especially interested in the neurobiological bases of emotion, emotion regulation, and emotional/personality development, including synchronization and coherence among neural subsystems and consolidation of synaptic networks through recurrent emotional states. In my theoretical writing I try to integrate neurobiological and psychological theory and findings. As for empirical work, my students and I have developed the “state space grid” method for analyzing observational data on socioemotional behaviour over development. But most of our work is devoted to dense-array EEG methods for studying emotion regulation in the brain. We are examining how cortical mechanisms that regulate negative emotions change with age, differ with personality subtypes, and potentially change in parallel with behavioural change when children undergo successful therapeutic interventions. Our research also looks at cortical responses to emotionally compelling faces in relation to age, familiarity, and personality/temperament factors.
Applied/Clinical Interests
Our research integrates brain and behavioural data to look at changes in emotion regulation that result from effective therapeutic intervention with "antisocial" children. I am also interested in the role of internal dialogue in personality and psychopathology.
