About me

I’m a freelance science writer and former online science editor at National Geographic. My writing has appeared in magazines and newspapers including National Geographic, NPR, Scientific American, Popular Mechanics, Science News, the Philadelphia Inquirer, Boulder Daily Camera, and more.

I write about various science topics — whatever captures my curiosity, really — but I gravitate toward the weird/gross/morbid, forensic science, and overlooked aspects of women’s health.

I live in Knoxville, TN, and part-time in Washington, DC.
