For the past year, Overheard has explored the journeys of photographers and scientists who are focusing a new lens on history. National Geographic presents In Conversation, a special podcast episode featuring explorer Tara Roberts, computer scientist Gloria Washington, and photographer Ruddy Roye. Through their dynamic work across maritime archeology, artificial intelligence, and photojournalism, they’re determined to reimagine Black history. We begin with National Geographic Explorer and Storytelling Fellow Tara Roberts, who talks to Overheard’s Amy Briggs about documenting the efforts of Black scuba divers and archaeologists in their search for the lost wrecks of ships that carried enslaved Africans to the Americas. We’ll also hear from computer scientist Gloria Washington of Howard University. She speaks with guest host Brian Gutierrez about her work developing “emotional” artificial intelligence. And finally National Geographic Storytelling Fellow Ruddy Roye traces his photographic journey with Overheard’s Peter Gwin—and turns his lens on the racial and civil conflicts that defined 2020.
