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.

Charles J. Limb, MD

Dr. Limb has studied the neuroscience of musical creativity for the last 15 years as Principal Investigator of the Sound and Music Perception lab, first at Johns Hopkins University, and now at UCSF. Throughout his career, Dr. Limb has combined his interests in music, auditory science, and the clinical treatment of hearing loss in diverse ways relevant to education, learning, neural plasticity and higher order cognition. Dr. Limb has published papers in a variety of peer-reviewed journals and given talks at various scientific conferences. His work has received international attention and has been featured by National Public Radio, TED, National Geographic, the New York Times, PBS, CNN, Scientific American, the British Broadcasting Company, the Smithsonian Institute, the Library of Congress, the Sundance Film Festival, Canadian Broadcasting Company, the Kennedy Center, San Diego Symphony, Baltimore Symphony Orchestra and the American Museum of Natural History.

Sheri L. Robb, PhD, MT-BC
Music Therapy Co-Investigator

Dr. Sheri L Robb is an Indiana University School of Nursing professor with international recognition for her Read more... expertise in pediatric music therapy and behavioral intervention research. She is a member of the IU Simon Comprehensive Cancer Center, and serves as Director for the Indiana Clinical and Translational Sciences Institute (CTSI) KL2 Young Investigator Program. Dr. Robb is a board-certified music therapist with degrees in music therapy and early childhood special education. She also completed a post-doctoral fellowship in behavioral oncology and cancer control at Indiana University, followed by a training award in clinical and translational research from the Indiana CTSI. Dr. Robb’s program of research focuses on development and testing of music interventions to manage distress and improve positive health outcomes in children and adolescents with cancer and their caregivers. Most recently, her team has begun incorporation of biomarkers to understand more fully how active music interventions work to mitigate cancer-related stress and its potential to improve immune function. Dr. Robb is an established investigator with fifteen years of continuous funding from the National Institutes of Health. She also led publication of Reporting Guidelines for Music-based Interventions to address calls for more transparent and accurate reporting in music intervention research.
