Empathy is crucial for the advancement of modern science and health research and Dr. Rachel Walker tells us why. Rachel is an Associate Director for the Center for Personalized Health Monitoring and professor at the University of Massachusetts Amherst. Most notably, she is the first nurse to be named an “Invention Ambassador” by the American Association for the Advancement of Science. Her work as a nurse inventor has been featured on NPR and in publications such as Scientific American and Forbes magazine. She is grateful to everyone; from grandmothers in East Baltimore to Malian midwives to bone marrow transplant recipients who have taught her to have some humility when seeking to understand what health and wellness means to different people, and how to get there. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
