  • Jad Abumrad - Host, Radiolab

    The son of a scientist and a doctor, Jad Abumrad did most of his growing up in Tennessee, before studying creative writing and music composition at Oberlin College in Ohio. Following graduation, Abumrad wrote music for films, and reported and produced documentaries for a variety of local and national public radio programs, including On The Media, Studio 360 with Kurt Andersen, Morning Edition, All Things Considered and WNYC's "24 Hours at the Edge of Ground Zero."

    Ellen Horne is the Executive Producer of Radiolab, WNYC's Peabody Award-winning program that examines big questions in science, philosophy and the human experience through compelling storytelling.  In 2003, Horne joined forces with Radiolab creator and host Jad Abumrad to build Radiolab into a thriving radio program.  Today, Radiolab is one of public radio's most popular shows.  Its podcasts are downloaded over 4 million times each month and the program is carried on 437 stations across the nation.

  • Tim Howard

    Tim came to Radiolab in 2009, after many years of playing music and working in non-profits, cafes, record stores, and dilapidated factories. He continues to write and record songs under the name Soltero, which can be heard here.  

  • Dylan Keefe - Director of Sound Design

    Still recovering from when Rolling Stone called him a “Rock n roll Judge Reinhold,” Dylan came to Radiolab after selling his soul at the crossroads of Marcy Playground Ally and Calle de WNYC. Carrying only a Fender P Bass and a shotgun microphone, Dylan was met at midnight first by Brooke Gladstone of On the Media, then John Hockenberry of The Takeaway and finally by a curly haired demon named Jad. All of whom detuned his bass and redirected his mic. Having actually wanted Carl Sagan to show up, Dylan decided the curly guy was close enough. Now he owes him his soul.

  • Matt Kielty

    Matt started at Radiolab as an intern. Now he works here. Around and in-between those two things, he lived in Minnesota, attended school in Arizona, tried to find himself, lived in Washington D.C., learned radio from Rob Rosenthal at the Salt Institute for Documentaries Studies, hung around This American Life, was awarded the Above the Fray fellowship to report in Uganda, and had a metal plate screwed into his wrist. He just realized this reads like Andy Mills' bio. He doesn't care.

  • Robert Krulwich - Host, Radiolab

    Robert Krulwich is co-host of Radiolab, WNYC's Peabody Award-winning program that examines big questions in science, philosophy and the human experience through compelling storytelling.  Today, Radiolab is one of public radio's most popular shows.  Its podcasts are downloaded over 4 million times each month and the program is carried on 437 stations across the nation. In addition to Radiolab, Krulwich reports for National Public Radio. “Krulwich Wonders” is his NPR blog featuring drawings, cartoons and videos that illustrate hard-to-see concepts in science.

  • Lynn Levy

    Before landing in radio, Lynn studied film at Wesleyan University and worked for several years in documentary film and television production.  Past projects have allowed her to hang out with UFO enthusiasts in Texas, watch robot battles in Georgia, and eat fantastic BBQ all over the place.  Now she's having new adventures as part of the Radiolab crew.  She spends a lot of her spare time admiring the dioramas in the American Museum of Natural History, and sometimes makes shoebox-sized dioramas of her own.

  • Andy Mills

    Before working for Radiolab, Andy had a lot of jobs, from being a research journalist in Southern Sudan to making fancy lattes in Denver, Colorado. To date he’s been a dishwasher, groundskeeper, paper boy, photographer, fund raiser, camp counselor, fast food burger-flipper, janitor, gardener, roofer, bus boy, missionary, ice cream scooper, barista, nanny, assistant professor, monk, equipment manager, waiter, television production assistant, secretary, painter and K-Mart Santa Clause. Now, when not producing stories for the radio, he writes short stories, performs live storytelling multi-media shows, and rides his bicycle all over New York City.

  • Malissa O'Donnell

    Malissa spent far too much time during college at WVKR, Vassar College’s radio station, as Director of News + Public Affairs and then as General Manager. Post-grad, she worked with the likes of Blue Man Group, New York Theatre Workshop, 101 Productions and New York Stage and Film, and MFAed in Theatre Management & Producing from Columbia University. Now she’s back (like a data track) to support the mind-boggling awesomeness that is Radiolab. Her best friends (who are a plasma physicist, chemical engineer, astrophysicist/computer scientist, doctor, chemist, acoustics physicist and another doctor), finally think she’s cool.

  • Kelsey Padgett

    Kelsey comes to Radiolab and the northeast from that loud and beautiful state that used to be a country, Texas. Yes, her family does own horses, and no, she hadn't seen snow before last winter. She's worked wrangling undergrad DJs in college radio, grocery carts at a co-op, horses on a tourism ranch, and hosts at a classical station. Now living in Brooklyn, she's extremely excited to be working her dream job with the Radiolab family, and spends a lot of her free time looking for good trees to climb.

  • Molly Webster

    Best described as someone who likes to "sit in the woods and stare," Molly fell in love with science in the ponds, wildlife, and fields of Ohio. She studied biology as an undergrad, and then spent time living on couches searching for a destiny she could only describe as "writing about science," at which point Molly wound her way to NYU's science reporting program to become a journalist. As one, she's had the jam-packed experience of reporting and producing stories for radio, magazine and Live events, including Scientific American and National Geographic Adventure; the World Science Festival; and WNYC's The Takeaway and Freakonomics Radio. It feels pretty surreal to call Radiolab home, but that's not stopping her from saying that it's so.

  • Soren Wheeler - Senior Editor, Radiolab

    Soren Wheeler is the Senior Editor at Radiolab, where he plays a variety of roles, including producer, editor, and reporter. He also oversees the development of future content. Before coming to radio, Soren spent 10 years working with science teachers and writing about how kids learn science. He was a project coordinator at the Association for the Advancement of Science, where he co-authored the book Atlas of Science Literacy. He then went on to get a Master’s degree in science writing at Johns Hopkins University. Soren has won awards for production on radio pieces about coincidence and statistics, the periodic table, and the story of a woman waking up from a coma.

  • Jamie York - Senior Producer, Radiolab

    Jamie is the Senior Producer of Radiolab where he oversees the staff and the short and long-term editorial planning. Jamie comes to Radiolab after years of reporting and producing for WNYC’s On the Media, NPR and the BBC. Most recently he’s reported stories from China, Malaysia, Poland, India and Louisiana. Before that Jamie was lucky enough to work with, and learn from, Dave Isay, the Kitchen Sisters, Jay Allison and Joe Richman.  He learned radio from the good folks at the Salt Institute for Documentary Studies. After years of enviously listening in on how Radiolab gets made he’s thrilled to be part of the process.
