I’m a columnist at CNN.com, writing mostly about social change and human rights. I also head up CNN’s new Change the List project. I’ve covered a range of events and topics, from video gaming addiction in South Korea to the Gulf Coast oil disaster, slavery in West Africa and climate change in Alaska. I co-produced CNN iReport’s “Walk in Our Shoes” project, which won a Webby Award for best online video mash-up. My story on “Slavery’s Last Stronghold,” which was part of CNN’s Freedom Project, won a Foreign Press Association award. I’m from Oklahoma and love the outdoors.
