Robert L. Park is a professor of physics and former chair of the Department of Physics at the University of Maryland. He divides his time between the University and the Washington, DC office of the American Physical Society, which he opened in 1982. Author of more than a hundred technical papers on the structure and properties of single-crystal surfaces, Professor Park now devotes himself to helping the public distinguish genuine scientific advances from foolish and fraudulent claims. A frequent guest on news programs, he posts a provocative and widely-read weekly column on the internet, and is the author of Voodoo Science: the Road from Foolishness to Fraud.
