Public Health Educator · DrPH, MPH

Infectious disease, health policy & plain talk.

A doctorate, a decade in the field, and zero patience for spin. I translate what's actually happening in public health into language that makes sense. My work spans infectious disease, health policy, and the science of how we communicate risk.

About

Hi, I'm Olivia.

Hi, I'm Olivia! I hold a doctorate and a master's in public health, and I work at the intersection of infectious disease, health policy, and strategic communications. Boston born and raised, now based in Denver.

Most of what I do is translation — taking new studies, data, and public health findings and turning them into plain language that's actually useful. I'll walk you through what the evidence says, what it doesn't, and why it matters for your everyday life.

And when someone's playing fast and loose with the science behind your health, I'm not shy about saying so. Clear, honest, and always backed by the evidence.

This is my home base — for the podcast, for connecting on Threads, and for the interviews and commentary I've been part of along the way. Welcome in. And if you'd like to partner, get in touch.

The views I express online and in any published interviews or articles are my own and do not reflect those of my employer or any affiliated organizations.
