Veeraraghavan is co-author of the paper, “Does Fake News Create Echo Chambers?” It was also written by Ken Moon, Wharton professor of operations, information and decisions, and Jiding Zhang, an assistant operations management professor at New York University Shanghai who earned her doctorate at Wharton.
