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. My freelance work has appeared in The New York Times, The Atlantic, Science, Hakai, High Country News, and many other publications. I’m a former science reporter for the Los Angeles Times, where I focused on climate change. 

Several of my stories have been anthologized in the Best American Science and Nature Writing series, including features for The Atlantic on phosphorus (also the runner-up for the science writing award from the American Society of Journalists and Authors) and invasive earthworms (also a finalist for the Society of Environmental Journalists’ Outstanding Feature Story Award). My story on backcountry ice skating for Adventure Journal was listed as notable in The Best American Science and Nature Writing 2020. Other awards include the Best of the Northwest Science Writing Award from the Northwest Science Writers Association, a Silver Excel award for feature writing from Association & Media Publishing, and the 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 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 2021-2022 Knight Science Journalism Project Fellow, a 2016 writer-in-residence at the Wrangell Mountain Center in McCarthy, Alaska, a 2015 Open Notebook/Burroughs Wellcome Fund Fellow at The Open Notebook, and a 2014 AAAS Mass Media Science and Engineering Fellow at the LA Times.

I have a bachelors degree and a PhD in geology. For my doctoral research, I studied polar ice cores to understand the Earth’s climate and why it changes. To learn more, read my award-winning Terra magazine story.
