Dr. Koen’s research focuses broadly on the cognitive neuroscience of learning and memory across the lifespan. His specific focus on understanding the neurocognitive processes that give rise to episodic memory – memory for unique events from one’s past – and how memory changes across the lifespan. He uses a combination of behavioral, psychophysiology (EEG and eye tracking), computational modeling, neuroimaging (fMRI), and neuromodulation (TMS) approaches to examine the cognitive processes and neural substrates that support episodic memory in young and healthy older adults.
