Dr. Charles Geier is a developmental cognitive neuroscientist interested in understanding the neurodevelopment of brain systems underlying goal-directed and habitual behaviors, and how these systems interact across contexts to impact health and disease

BS Biological Sciences Ohio University 2000


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.
