Marisa Peñaloza is a senior producer on the National Desk. From breaking news to documentary-style features, Peñaloza's productions are among the signature pieces heard on NPR's award-winning newsmagazines Morning Edition, All Things Considered and Weekend Edition.

Her work has covered a wide array of topics, from hurricanes, education, immigration, politics and the economy to homeland security and litigation. She has also produced investigative reports and traveled across the U.S. and the world for NPR.

Although Peñaloza's permanent assignment is on the National Desk, she occasionally travels overseas on assignment. She traveled to Haiti soon after the 2010 earthquake hit and she's gone back several times to follow the humanitarian organizations working on the island nation. She's covered education in Peru and a dengue outbreak in El Salvador, the Madrid train bombings in Spain as well as the Tsunami in Banda Aceh, Indonesia.

In 2011, she traveled to Honduras to cover the sock industry as part of a two-part series on globalization and to El Salvador to produce a series of stories on immigration. Her past productions include coverage of the Elian Gonzalez custody battle from Miami, protests outside the Navy site on the Island of Viequez, in Puerto Rico, the aftermath of the crash of the American Airlines flight 587 in New York. She contributed to NPR's 9/11 coverage. Peñaloza was one of the first NPR staff members to arrive on the Virginia Tech campus to cover the shootings in 2007. She was on assignment in Houston waiting for hurricane Ike to make landfall in September 2008, and she continues to produce coverage of New Orleans recovery after Katrina.

An award-winning journalist, Peñaloza was honored with the 2011 National Headliner Award in investigative reporting and the Grand Award for a series of stories looking at the role of confidential informants - people who pose as criminals so they can provide information to federal law enforcement; except sometimes, these informants are criminals themselves.

In 2009, Peñaloza was honored with several awards for contribution to "Dirty Money," an enterprising four-part series of stories that examined law enforcement's pursuit of suspected drug money, which they can confiscate without filing charges against the person carrying it. Local police and sheriffs get to keep a portion of the cash. The awards for "Dirty Money" include the Society of Professional Journalists' Sigma Delta Chi Award in the investigative reporting category; the Scripps Howard Foundation's National Journalism Foundation Award; and the RTNDA Edward R. Murrow Award in the "best website" category.

In 2008, Peñaloza was honored by the Education Writers Association with its "National Award for Education Reporting" for a year-long NPR on-air and online series following a Baltimore-area high school's efforts to improve student achievement. She won the Nancy Dickerson Whitehead Award for Excellence in Reporting on Drug and Alcohol Problems in 2007, for a five-part series of stories that examined this country's gains and losses since the war on drugs was launched more than thirty years ago, "The Forgotten Drug Wars." She is the recipient of the 2005 unity award for producing Debbie Elliott's Brown vs Board of Education piece, "Before Desegregation: The Education Migration."

In 2003, Peñaloza produced a two-part story entitled "Corruption at the Gates." NPR correspondent John Burnett and Peñaloza discovered that some U.S. border officials are on the take, illegally passing drugs and immigrants into the country in return for bribes. The reports won them a National Headliner Award in the investigative reporting category.

In 2001, "Globalization and the Return of Dengue" won Peñaloza the Pan American Health Organization's Award for Excellence in International Health Reporting. The story was part of a series of stories for NPR and American Radio Works on globalization and disease.

Peñaloza made the leap from television to radio in 1997, when she joined NPR's National Desk. Before coming to NPR she was a staff at the local NBC station and a freelance writer for the Fox affiliate in Washington, DC.

Peñaloza graduated from the George Washington University in Washington, DC, with bachelor's degrees in Broadcast Media and Political Science.
