Research

We use behavioral measures (e.g., cognitive tasks, eye tracking) and multi-modal functional neuroimaging (e.g., task-based functional MRI, resting state fMRI) to examine (1) the normative neurodevelopment of reward and control-related brain systems during adolescence and young adulthood, (2) how the interaction of these systems contributes to health-related behaviors and illness, including consummatory behavior and obesity, smoking cigarettes, and depression, and (3) how initially reward- or goal-directed behaviors 'evolve' into habits in adolescents and young adults. We are particularly interested in applying advanced statistical methods (e.g., GIMME, time-varying vector autoregressive models, etc.) to acquired fMRI time series data to characterize intra-individual change and inter-individual differences in intra-individual change in brain connectivity between task-relevant regions of interest that underlie decisions and habits.
