I’m an independent journalist covering science and the environment from Portland, Oregon. I write stories—mostly features—about how the world works and how humans are changing it. I’m a former science reporter for the Los Angeles Times, where I focused on climate change. My freelance work has appeared in The New York Times, The Atlantic, Science, Hakai, High Country News, and many other publications. I also host podcasts for Scientific American‘s 60-Second Science.

My story for The Atlantic on invasive earthworms was anthologized in the 2021 Edition of The Best American Science and Nature Writing. I was honored to win the 2019 Best of the Northwest Science Writing Award from the Northwest Science Writers Association, a 2016 Silver Excel award for feature writing from Association & Media Publishing, and the 2014 Grand Gold Award for feature writing from the Council for the Advancement and Support of Education, Region VIII. I’ve been a finalist for the Society of Environmental Journalists’ Outstanding Feature Story Award, the American Geophysical Union’s Walter Sullivan Award for Excellence in Science Journalism, and a Science in Society Journalism Award from the National Association of Science Writers.

I was a 2014 AAAS Mass Media Science and Engineering Fellow, a 2015 Open Notebook/Burroughs Wellcome Fund fellow, and a 2016 writer-in-residence at the Wrangell Mountain Center in McCarthy, Alaska.

I have a bachelors degree and a PhD in geology. My doctoral research focused on reconstructing the composition of past atmospheres using polar ice cores to better understand the Earth’s climate and why it changes. To learn more, read my award-winning Terra magazine story.
