Biography
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, and neuroimaging (fMRI) approaches to examine the cognitive processes and neural substrates that support episodic memory in young and healthy older adults.

Approach to Mentoring
I aim to create a collaborative environment in both my lab and classroom that continually challenges students to cultivate skills that will support success in their chosen career path. I also support students through constant encouragement, celebration of their successes, and tailor my level of 'hands-on' engagement to the need of each student.Representative Publications
