While working on staff at WNYC, Abumrad began tinkering with an idea for a new kind of radio program.  That idea evolved into one of public radio’s most popular shows today – Radiolab.  Abumrad hosts the program with Robert Krulwich and also serves as one of its producers.  The program won the prestigious George Foster Peabody Award and explores big questions in science, philosophy and mankind.  Under Abumrad’s direction, the show uses a combination of deep-dive journalism, narrative storytelling, dialogue and music to craft compositions of exploration and discovery.  Radiolab podcasts are downloaded over 10 million times each month and the program is carried on more than 500 stations across the nation and internationally. 

Abumrad is also the Executive Producer and creator of Radiolab's More Perfect, a podcast that explores how cases deliberated inside the rarefied world of the Supreme Court affect our lives far away from the bench.

Abumrad was honored as a 2011 MacArthur Fellow (also known as the Genius Grant).  The MacArthur Foundation website says:  “Abumrad is inspiring boundless curiosity within a new generation of listeners and experimenting with sound to find ever more effective and entertaining ways to explain ideas and tell a story.” 

Abumrad also produced and hosted The Ring & I, an insightful, funny, and lyrical look at the enduring power of Wagner's Ring Cycle.  It aired nationally and internationally and earned ten awards, including the prestigious 2005 National Headliner Grand Award in Radio.
