I am an author and freelance health and science writer based near Washington, D.C.  My expertise is in health, nutrition, medicine, environmental sciences, physics and astronomy.


I hold a master’s degree in environmental health science from Harvard School of Public Health and a degree in journalism from Temple University.


I am the author of three books: Spacefarers (2020), Food At Work (2005), and Bad Medicine (2003).  I also have written more than 500 newspaper, magazine and web articles for periodicals such as The Washington Post and Smithsonian Magazine.  I am a columnist for LiveScience and for Mercury magazine.  Also from 1997 to 2014, I was a contributing joke writer for The Tonight Show with Jay Leno, the likely contributor to any science- or health-oriented joke you heard on that show, until its demise.


My work has been translated into nearly a dozen languages.  Copies or sections of Food At Work are available in French, Spanish and Portuguese.  Bad Medicine is available in Korean and Chinese with a Russian translation scheduled for 2013.

As for the photos, that’s me on the right presenting Food at Work in Santiago, Chile.  That’s me in the left, too, wearing the same suit somewhere else.
