I am a journalist focused on food as a lens through which to explore the world. I am a fellow at the Institute for Food and Development Policy in Oakland, USA, and a former visiting scholar at the Cocoa Research Centre in St. Augustine, Trinidad. I was the host of the PBS series Ethical Markets and contributing author of the award-winning book based on the series, titled "Ethical Markets: Growing the Green Economy." I also wrote "Bread, Wine, Chocolate: The Slow Loss of Foods We Love" that highlighted changes in food told through bread, wine, chocolate, coffee and beer, and was named one of the Best Food Books of 2016 by Smithsonian. I created The Slow Melt chocolate podcast, named Best Food Podcast of 2017 by SAVEUR. I am a contributor to NPR's Good Food and have written for publications including The Wall Street Journal, The Guardian and VICE.
