Dr. Miller is interested in the psychological and neural processes underlying human memory and decision-making. His research employs a variety of techniques, including functional magnetic resonance imaging (fMRI), event-related potentials (ERP), transcranial magnetic stimulation (TMS), split-brain studies, and signal detection analysis. These studies range from investigations into prefrontal and parietal cortex activity associated with shifts in decision criteria to attempts to uncover the functions of the parietal lobe during successful retrieval. A major component of our research examines the sources variability of individual patterns of brain activity during an episodic memory task. Ultimately, our goal is to use these neuroscientific studies to understand the processes of the mind when remembering a past event, and to appreciate the uniqueness of these processes at the individual level.
