Before that, she was a reporter at WNYC, New York Public Radio, where she contributed stories to Radiolab, On the Media, United States of Anxiety, The Brian Lehrer Show and more. Aronczyk covered science and health, and she fondly remembers collecting saliva from voters to measure stress, corresponding with the Unabomber and using nose swabs to solve a classic office mystery: who came to work sick? She was also the lead reporter on the award-winning 10-story companion series to PBS' "The Emperor of All Maladies," presented by NPR and WNYC.

Aronczyk also teaches audio journalism at the Newmark Graduate School of Journalism at CUNY.
