David Baron oversees The World's coverage of science and medicine, with a special focus on the health of people in developing nations.

A journalist, author, and broadcaster for more than twenty years, David decided early on to merge his passion for science (he majored in physics at Yale) with his love of public radio. He began his career as science reporter for WBUR in Boston and later moved to NPR, where he reported on science, medicine, technology and the environment for All Things Considered, Morning Edition, and Weekend Edition, and served as substitute host of Talk of the Nation: Science Friday. David joined The World in 2005 and has overseen several of the show's major series, including "The Global Race for Stem Cell Therapies," "The Forgotten Plague: Malaria," and "Cities of the Poor."

David's work has garnered numerous honors, including a duPont-Columbia Award as well as science journalism prizes from the American Medical Association, American Society for Microbiology, and American Association for the Advancement of Science. His 2003 book, The Beast in the Garden, received a Colorado Book Award.

In pursuit of stories, David has braved erupting volcanoes (in Iceland and Montserrat), endured swarms of African safari ants (in Uganda), 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.
