Ari Daniel
Ari Daniel is a reporter for NPR's Science desk where he covers global health and development.
Ari has always been drawn to science and the natural world. As a graduate student, Ari trained gray seal pups (Halichoerus grypus) for his Master's degree in animal behavior at the University of St. Andrews, and helped tag wild Norwegian killer whales (Orcinus orca) for his Ph.D. in biological oceanography at MIT and the Woods Hole Oceanographic Institution. For more than a decade, as a science reporter and multimedia producer, Ari has interviewed a species he's better equipped to understand – Homo sapiens.
Over the years, Ari has reported across five continents on science topics ranging from astronomy to zooxanthellae. His radio pieces have aired on NPR, The World, Radiolab, Here & Now, and Living on Earth. Ari formerly worked as the Senior Digital Producer at NOVA where he helped oversee the production of the show's digital video content. He is a co-recipient of the AAAS Kavli Science Journalism Gold Award for his stories on glaciers and climate change in Greenland and Iceland.
In the fifth grade, Ari won the "Most Contagious Smile" award.
