She initiated highly influential Congressional hearings on a wide range of health issues, including cancer prevention and treatment and the safety of medical products.

She is currently on the Board of Directors of two nonprofit organizations – the Congressionally mandated Reagan Udall Foundation and the Alliance for a Stronger FDA. She was previously the chair of the Women’s Health Promotion Council, appointed by the Governor of Maryland.

Dr. Zuckerman is the author of five books, several book chapters, dozens of articles in medical and academic journals, and in newspapers across the country. Her policy work has resulted in news coverage on all the major TV networks, including ABC, CBS, NBC, CNN, Fox News, public television, “60 Minutes,” “20/20,” “Voice of America,” National Public Radio, and in major U.S. print media such as The New York Times, Wall Street Journal, The Washington Post, The Washington Times, Los Angeles Times, Boston Globe, USA Today, Detroit Free Press, New York Daily News, Newsweek, Time, U.S. News and World Report, Family Circle, New Yorker, Glamour, Self, as well as many other newspapers, magazines, and radio programs.
