Research Focus


My research is focused broadly on the organization and neural substrates supporting human memory.  Through the use of parallel and converging cognitive neuroscience methodologies, my research seeks to better understand how the brain stores new information, maintains information in mind, and retrieves previously stored memories.  My research has contributed to the emerging consensus that the hippocampus, an area of the brain that has long been implicated in supporting memory for information held in long-term memory, also contributes to memory performance for recently studied information (Olsen et. al., Journal of Neuroscience, 2009).   My current research is centered on the proposal that the hippocampus enables memory by forming associations among disparate elements presented across space and time, and further, by performing the comparison of stored memory representations with current perceptual input (Olsen et. al., Frontiers in Human Neuroscience, 2012).   It is my hope that, ultimately, through careful study of the hippocampus and the cortical systems supporting memory, my research will enable better understanding and treatment of memory impairments associated with healthy aging, brain damage, and psychiatric illness.
