Julene Johnson, PhD
Network Co-Director

Dr. Julene K Johnson is a cognitive neuroscientist with an undergraduate degree in music. She is a Professor Read more... in the UCSF School of Nursing's Institute for Health & Aging and co-director of the Sound Health Network. She has a long-standing interest in studying music and health in both healthy aging and persons living with dementia. Her previous work investigated preserved music skills in persons with Alzheimer disease and understanding the relationship between brain and music recognition in various neurodegenerative diseases. In 2010, she was a Fulbright Scholar in Jyväskylä, Finland where she studied how community choirs help promote wellbeing among older adults. Funded by the National Institute on Aging, Dr. Johnson recently completed a large cluster-randomized trial that examined the effects of a community choir on the health and wellbeing of culturally diverse older adults. Dr. Johnson also examines the historical roots of music in nineteenth-century neurology and psychology literature, which helps frame interdisciplinary research questions about music, brain, and health. She is a co-author of the NEA Guide to Community-Engaged Research in the Arts and Health (2016). In her spare time, she plays the flute and kantele and sings in a community choir.
