Peter Bandettini interviews Dr. Rosanna Olsen, a senior scientist at the Rotman Research Institute and the University of Toronto. She is pioneering what we know about human memory and its associated structures, primarily focusing on the hippocampus, the role it plays, and how it changes with age and neurological diseases. Her work has shed light on how the hippocampus facilitates the flexible binding and comparison of new and existing information. She has also shown how visual exploration reveals memory processes, and has uncovered promising early dementia biomarkers based on measures of visual exploration and hippocampus. Dr. Olsen is also a leader in education. She is co-lead of the Research Training Center in Toronto, disseminating essential knowledge and skills to younger scientists, and is chair-elect of the OHBM education committee. She is also the leader of a consortium organized to reach a consensus on hippocampus segmentation. Lastly she's an avid and accomplished runner, having run the Boston Marathon, as well as many others.We hope you enjoy the conversation! Episode ProducersOmer Faruk GulbanXuqian Michelle Li
