Research News

20 Nov 2013: New paper with Andrew Titmus & Michael Ford on distribution and abundance of plastic debris out in PLOS ONE! The data is archived at CCE LTER's Datazoo repository. Also check out Figshare for even more information. There's an informal blog post too.

22 Oct 2013: Deb Goodwin and I have a new paper out on barnacles eating plastic in the North Pacific Subtropical Gyre. The paper is freely available at PeerJ. I also wrote a blog post about it, which was picked up by The Atlantic, Grist Magazine, Huffington Post Canada, and author Margaret Atwood.

May 2012: My co-authors and I published a paper on how plastic debris is altering open ocean habitats - check it out here!

Research Description

For my Ph.D. at the Scripps Institution of Oceanography, I studied the abundance and ecological implications of microplastic debris in the North Pacific Subtropical Gyre, with a focus on zooplankton and the invertebrates that live attached to floating debris. You can read the abstract or the entire dissertation online

I'm honored that my dissertation won a 2013 Chancellor's Dissertation Medal at UC San Diego.

SEAPLEX: Scripps Environmental Accumulation of Plastic Expedition

In 2009, I served as Chief Scientist for a student-led expedition to explore the problem of plastic in the North Pacific Gyre. From August 2-21, 2009, a group of doctoral students and research volunteers from Scripps Institution of Oceanography at UC San Diego embarked on an expedition aboard the Scripps research vessel New Horizon exploring the problem of plastic in the North Pacific Gyre.
