How does a medical doctor go from managing patients’ blood sugar and kidney failure to designing global health policy, and now to leading action on climate change?

Sandro Demaio joins Salma to discuss his career from working as a clinician to leading health and climate change work for the Western Pacific Region of the WHO. They explore the skills that transfer across his roles in medicine and public health—systems thinking, communication, and entrepreneurship—and examine why public health is often uncomfortable with that last word. They also discuss Sandro’s experience as a public communicator and advocate, from newspaper columns to a Netflix series to getting national vaping legislation through Parliament. Finally, they turn to climate change and discuss how to keep working on the same problems, while reframing the narrative, when the political or social environment isn’t receptive.

This episode invites you to reflect on why careers are rarely well-defined or linear, which skills transfer across roles, and how an entrepreneurial mindset can help public health keep pace with a changing world.
