Before joining NPR, Warner was a senior reporter for American Public Media's Marketplace, where he endeavored to make the economics of American health care vivid and engaging. He's used puppets to illustrate the effects of Internet diagnoses on the doctor-patient relationship. He composed a Suessian cartoon to explain why health care job growth policies can increase the national debt. His musical journey into the shadow world of medical coding won the 2012 Best News Feature award from the Third Coast International Audio Festival.

Prior to Marketplace, Warner was a freelance radio producer reporting from conflict zones around the world. He climbed mountains with smugglers in Pakistan for This American Life, descended into illegal mineshafts in the Democratic Republic of Congo for Marketplace's "Working" series, and lugged his accordion across Afghanistan on the trail of the "Afghan Elvis" for NPR's Radiolab.

Warner's radio and multimedia work has won awards from Edward R Murrow, New York Festivals, AP, PRNDI, and a Sigma Delta Chi award from the Society of Professional Journalists. He has twice won Best News Feature from the Third Coast International Audio Festival in 2009 and 2012.

Warner earned his degree in English at Yale University. He is conversant in Arabic.

Two minutes into Present Tense, a short film made by three high school students in a fishing village in the East African island of Zanzibar, a set of subtitles lay out their mission:

Hundreds of mourners in Burundi spilled out of a funeral service Tuesday at a Catholic church, their hands raised and their palms open in what is now a global meme against police violence.

They were there to mourn an engineering student, Theogene Niyondiko, 28. He was shot last Friday by police during a protest against President Pierre Nkurunziza.

It's a problem in a taxi economy if people don't like getting into cabs that are driven by strangers. A cab driver is a stranger almost by definition. But in the high-crime city of Nairobi, Kenya, people prefer to call up drivers they know or who their friends recommend.

An American named Jason Eisen spent years in Nairobi as a consultant until he had his big idea. He built an app that doesn't just tell you which taxis are close by, like Uber does. It also assigns the driver a trust score, by scouring riders' contacts and social media.

The world's largest refugee camp is also a giant social experiment.

Take hundreds of thousands of Somalis fleeing a war. Shelter them for 24 years in a camp in Kenya run by the United Nations. And offer different opportunities than they might have had if they'd stayed in Somalia.

The Kenyan government wants the experiment to end — soon. It's pushing the refugees to return to their home in Somalia, though the camp called Dadaab is the only home many have known.
