Does public health belong to people with a specific perspective, or is it—as the term implies—for the public at large?

Today’s episode is different. Dean Sandro Galea, Dean and Distinguished Professor at WashU School of Public Health, returns to the podcast to discuss the Purple Public Health Project (PPHP), a new initiative he is launching with Salma. The PPHP aims to start a conversation about how public health thinks, acts, and communicates so we can reach people of all stripes, ideologies, and perspectives. Using concrete examples, they discuss whether public health should be grounded in science or values, or both. They also explore what each one of them thinks success would look like.

Join Salma and Dean Galea as they commit to this process of thinking rigorously in public about public health and contribute to shifting the thinking of the field.
