I turn rigorous research into stories people actually want to read.

My reporting spans health, medicine, biology, technology, and more. I've written for more than 20 outlets — from nuanced news and features at MIT Technology Review and The Sick Times to accessible health journalism at SELF, Healthline, and WebMD.

Before going freelance, I was Senior Editor at What to Expect, where I built and managed a team of health writers, oversaw all health content, and helped modernize the #1 pregnancy app on iTunes and Android.
