Dr. Koen’s research focuses on the cognitive neuroscience of learning and memory. His research aims to understand the neural processes that support encoding of memories that can be subsequently recollected. Another central question of his research program is to understand how episodic memory - memory for unique past events - changes across the lifespan. Dr. Koen uses a variety of behavioral (modeling, eye tracking), neuroimaging (fMRI, EEG), and neuromodulatory (TMS) techniques to address these questions. In addition, he investigates the link between the brain and memory by working with patients diagnosed or at elevated risk of Alzheimer’s disease, and with amnesic patients.
