Devra Davis

Devra Lee Davis (born June 7, 1946) is an American epidemiologist, toxicologist, and author of three books about environmental hazards. She was founding director of the Center for Environmental Oncology at the University of Pittsburgh Cancer Institute, and is a former professor of epidemiology at University of Pittsburgh Graduate School of Public Health. She has served on several governmental and non-governmental organizations, conducting research and advocacy into effects of pesticides, asbestos, and wireless radiation on human health, especially cancers.

Davis is the founder and president of the Environmental Health Trust, a non-profit organization which argues that mobile devices, WiFi, 5G, and other radio-frequency systems pose a health risk to humans and the environment. She has been called a "crusader in the fight over cell phone safety" and believes that radio frequencies could cause cancer. Such claims have been challenged by critics as being bereft of credible arguments. Provided by Wikipedia
