My research focuses on the role that emotion and attention-related brain systems play in social-emotional development. I am particularly interested in what happens to emotion, attention, and social development when the frontolimbic brain system is modified--e.g., by typical or atypical development, by intervention, or by brain injury. By understanding these brain mechanisms we may discover ways to promote healthy, adaptive social-emotional development. My work examines multiple levels (basic and applied), from multiple perspectives (neural, psychological, and philosophical), and with a variety of methods and approaches (neuroimaging, psychophysiological, eye tracking, interventions, lesion patients, and high-risk populations). Students are a central part of my research program; I am continually developing and improving upon training materials, manuals, and protocols to facilitate students' participation in research, and maximize their training and contribution.
