My research focuses on the origins, development, and basic processing mechanisms involved in social attention, self-regulation, social interaction, and decision making. These complex behaviors are multi-determined and require analysis at multiple time scales with a diverse set of tools including eye tracking, motion analysis, neuroimaging (EEG, fNIRS), physiological measures (ECG, pupillometry), observational coding, and online studies. Current projects include the temporal dynamics of joint attention, the development of infants’ physiological and behavioral emotion regulation, the origins and early development of predictive processing during social interactions, the functional implications of neural and behavioral synchrony, and real-world decision making involving photo sharing, secure vs. insecure websites, and face GANS (generative adversarial networks). Most of these projects are highly collaborative and involve developmental, social, cognitive, and computer scientists.
