Palca began his journalism career in television in 1982, working as a health producer for the CBS affiliate in Washington, DC. In 1986, he left television for a seven-year stint as a print journalist, first as the Washington news editor for Nature, and then as a senior correspondent for Science Magazine.

With Flora Lichtman, Palca is the co-author of Annoying: The Science of What Bugs Us (Wiley, 2011).

As NPR's Miami correspondent, Greg Allen reports on the diverse issues and developments tied to the Southeast. He covers everything from breaking news to economic and political stories to arts and human interest features. He moved into this role in 2006, after four years as NPR's Midwest correspondent.
Allen was a key part of NPR's coverage of the 2010 earthquake in Haiti, providing some of the first reports on the disaster. He was on the frontlines of NPR's coverage of Hurricane Katrina in 2005, arriving in New Orleans before the storm hit and filing on the chaos and flooding that hit the city as the levees broke. Allen's reporting played an important role in NPR's coverage of the aftermath and the rebuilding of New Orleans, as well as in coverage of the BP oil spill which brought new hardships to the Gulf coast.
As NPR's only correspondent in Florida, Allen covered the dizzying boom and bust of the state's real estate market, the state's important role in the 2008 presidential election and has produced stories highlighting the state's unique culture and natural beauty, from Miami's Little Havana to the Everglades.
Allen has spent more than three decades in radio news, the first ten as a reporter in Ohio and Philadelphia and the last as an editor, producer and reporter at NPR.
Before moving into reporting, Allen served as the executive producer of NPR's national daily live call-in show, Talk of the Nation. As executive producer he handled the day-to-day operations of the program as well as developed and produced remote broadcasts with live audiences and special breaking news coverage. He was with Talk of the Nation from 2000 to 2002.
Prior to that position, Allen spent three years as a senior editor for NPR's Morning Edition, developing stories and interviews, shaping the program's editorial direction, and supervising the program's staff. In 1993, he started a four year stint as an editor with Morning Edition just after working as Morning Edition's swing editor, providing editorial and production supervision in the early morning hours. Allen also worked for a time as the editor of NPR's National Desk.
Before coming to NPR, Allen was a reporter with NPR member station WHYY-FM in Philadelphia from 1987 to 1990.
His radio career includes serving as the producer of Freedom's Doors Media Project — five radio documentaries on immigration in American cities that was distributed through NPR's Horizons series — frequent freelance work with NPR, Monitor Radio, Voice of America, and WHYY-FM, and work as a reporter/producer of NPR member station WYSO-FM in Yellow Springs, Ohio.
Allen graduated from the University of Pennsylvania in 1977, with a B.A. cum laude. As a student and after graduation, Allen worked at WXPN-FM, the public radio station on campus, as a host and producer for a weekly folk music program that included interviews, features, live and recorded music.
Bill Chappell is a blogger and producer who works with NPR's Morning Edition and Digital Media group. In addition to coordinating Web features, he frequently contributes to NPR's blogs, from The Two Way and All Tech Considered to The Salt.
Chappell's work at NPR has ranged from being the site's first full-time homepage editor to leading the London 2012 Olympics blog, The Torch. His assignments have included being the lead web producer for NPR's trip to Asia's Grand Trunk Road, as well as establishing the Peabody Award-winning StoryCorps on NPR.org.
In 2009, Chappell was a key editorial member of the small team that redesigned NPR's web site. One year later, the site won its first Peabody Award, along with the National Press Foundation's Excellence in Online Journalism award.
At NPR, Chappell trains both digital and radio staff to use digital tools to tell compelling stories, in addition to "evangelizing" — promoting more collaboration between departments. Other shows he has worked with include All Things Considered, Fresh Air, and Talk of the Nation.
Prior to joining NPR in late 2003, Chappell worked on the Assignment Desk at CNN International, handling coverage in areas from the Middle East, Asia, Africa, Europe, and Latin America, and coordinating CNN's pool coverage out of Qatar.
Chappell's work for CNN also included producing Web stories and editing digital video for SI.com, as well as editing and producing stories for CNN.com's features division. He also worked at the network's video and research library.
Before joining CNN, Chappell wrote about movies, restaurants and music for alternative weeklies, in addition to his first job: editing the police blotter.
From 2002-2003, Chappell served as editor-in-chief of The Trans-Atlantic Journal, a business and lifestyle monthly geared for expatriate Europeans working and living in the United States.
A holder of bachelor's degrees in English and History from the University of Georgia, he attended graduate school for English Literature at the University of South Carolina.
