Skepticism around public health policy, experts and institutions has left some researchers asking basic questions about their role and relationship with the public. Can public health be done better? Epidemiologist Erica Walker has a perspective on just that. She started off studying noise pollution, found her science wasn’t serving people as she hoped, and pivoted her approach in an effort to be more useful. Flora sits down with Walker to hear the story. Guest: Dr. Erica Walker is an assistant professor of epidemiology and director of the Community Noise Lab at Brown University in Providence, Rhode Island.
