I’m a freelance journalist covering science and the environment based in Portland, Oregon. I write stories about how the world works, and how humans are changing it.  I am a former science reporter for the Los Angeles Times, where I focused on climate change. My freelance work has appeared in The Atlantic, Science, Nature, Hakai, bioGraphic, Orion, NationalGeographic.com, and High Country News, among other places. I occasionally host podcasts for Science, Scientific American‘s 60-Second Science and The Dirtbag Diaries.

I also like to run, ski, make music, garden, cook, and bake bread, and I dabble in writing about these topics too. I’m aware that I have a problem with hobbies…

I have been honored to receive numerous awards and honors, including 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, the 2014 Grand Gold Award for feature writing from the Council for the Advancement and Support of Education, Region VIII, and an AAAS Mass Media Science and Engineering Fellowship. In 2018, I was a finalist for the American Geophysical Union’s Walter Sullivan Award for Excellence in Science Journalism, and in 2017, for a Science in Society Journalism Award from the National Association of Science Writers.

I was 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.
