Thomas Farley

I'm a pediatrician, epidemiologist, and public health expert currently living in Washington, DC. I've worked in public health at the local, state, and federal level, including stints as health commissioner for New York City and for Philadelphia. My textbook Prevention of Diseases in Populations will be published in August 2025. Healthscaping, my weekly newsletter on Substack (healthscaping.substack.com), discusses how we can make our everyday world healthier.
