Description: I always wanted to become a “serious scientist”, at least until I got to graduate school. Learning the difference between what you’re good at and what you love takes time and experimentation. The one through-line for me has always been a desire to heal our planet. There are so many ways to do that and the one I found, and will talk about, is using the power of local government to move markets in service of people and planet. Cities have enormous capacity to become catalysts for change. Using my scientific training to ask the right questions, assemble credible data, test my ideas, and evaluate outcomes has been key to my policy journey and my success. I will share specific examples from my career at the city and county levels of government – including tackling toxic chemicals in consumer products, greenhouse gas emissions, plastics, and more. In every instance I found myself using science rather than doing science. I will also share a tool I have found incredibly helpful in guiding my career decisions. I’ve seen it transform and embolden so many others as they embark on exploring the possibilities of their life’s journey.
