Gregory N. Derry is a professor of physics and former chair of the Physics Department at Loyola College in Maryland.  He teaches at all levels, maintains an ongoing research program in experimental surface physics (studying the structure and composition of alloy surfaces by using electron diffraction techniques), and does work on the epistemological issues involved in the science/religion relationship.  He has written an introductory book on the nature of scientific inquiry, What Science Is and How It Works (published by Princeton University Press), and recently finished a manuscript of a book on complementarity as a logical framework in which to view nature as both sacred and mundane.  Dr. Derry is chair of the Metanexus Local Society in Baltimore and his work has been funded by the National Science Foundation, Research Corporation, and the John Templeton Foundation.  He holds a B.S. degree from Union College and a Ph.D. from the Pennsylvania State University, both in physics.  Previous appointments include Lawrence Berkeley Laboratory and the University of North Carolina at Chapel Hill.
