I have 25 years of experience, and specialize in the field of journalism with specific knowledge in the areas of Congress, politics and science policy. I have published on such topics as the history of biological warfare, Congress and multi-drug resistant tuberculosis. I cover Congress and federal agencies as a Washington correspondent. Before that, I was a science writer for the world’s largest weekly science magazine for a decade, reporting from two dozen countries in North America, Europe and Africa. I also have worked for a leading biotech research institute and I have written a book on the origins of 20th Century biological warfare.
