David Baron is health and science editor for The World, a daily international news program co-produced by the BBC World Service, PRI, and WGBH in Boston. He oversees the show’s coverage of science, technology, the environment, and medicine, with a special focus on the health of people in developing nations.

An award-winning journalist, author, and broadcaster, Baron decided early on to merge his passion for science (he majored in physics at Yale) with his love of public radio. From 1987 to 2000, he was a regular contributor of science reports to NPR’s news programs – first while serving as science reporter for WBUR in Boston, and later as an NPR science correspondent and substitute host of Talk of the Nation: Science Friday. Baron left NPR in 2000 to write The Beast in the Garden (Norton), a book about mountain lions in America’s suburbs, and to teach science journalism at Boston University. He found his way back to public radio, and The World, in 2005.

In pursuit of stories, Baron has braved erupting volcanoes, endured swarms of African safari ants, and journeyed to the very bottom of the earth: the South Pole. When not on assignment, his preferred activity is hiking in the Rocky Mountains near his home in Boulder, Colorado.
