Chris Higgins’s pursuit took him all the way across the US. Chris’s public health roots propelled him to work on a problem that would become surprisingly important to the world around him. He began a journey to understand problems caused by perfluorochemical environmental contaminants. Back then, the right tools to measure these chemicals didn’t exist—and nobody expected them to behave the way they did.

  • “Unless you're involved in some kind of industrial accident, you usually don't get a very high dose of chemicals. So it's really the long-term chronic exposure, lifetime exposure that we worry about.”
