A Passion for Improving Lives

“I wake up every day excited to do what I love and make a difference. My decades of experience addressing some of the world’s most challenging health issues – from cancer, to birth defects, to cardiovascular disease – has made me an innovator, willing to think outside the box to find new, cost-effective solutions. I’m committed to improving health across the lifespan through application of robust scientific methods to advance prevention and improve healthcare for all people.”
