Explore our Global Impact

How should we respond to a demographic shift that will change how the world lives, learns, and works? Harvard Chan researchers are digging deep into cellular mechanisms, analyzing statistical patterns across decades of health data, exploring how connection with others is protective, and tracking down other clues to healthier and happier aging.

Violence and trauma take many forms. Harvard Chan researchers are using scientific rigor to understand how damage to the body and spirit can be prevented, and develop ways to repair the effects of violence and build resilience in the future.

Climate change is one of our greatest public health challenges—but also one of our best opportunities for global progress. Harvard Chan researchers are uncovering the human toll of our changing environment and crafting solutions.

From fast food to no food, from the obesity epidemic sweeping the globe to social isolation and unhappiness, we’re still plagued by barriers to human thriving. The links between our health and how we feel, interact and live are complex and clouded. But thanks to the work of Harvard Chan researchers the path forward has never seemed clearer.

Humans and pathogens are locked in a bitter arms race—and the pathogens are winning. They are evolving to resist our best medicines, and humanity’s pipeline of effective antibiotic weapons is empty. The next pandemic is a matter of when, not if. Harvard Chan researchers are fighting on many fronts to make sure humanity is ready when the next outbreak inevitably arrives.
