Isn't Judy Wood a "Dental Materials Engineer"?   

 Judy has some experience in that field, but it's not her specialty. From her bio (on her tripod page): B.S. (Civil Engineering, 1981) (Structural Engineering), M.S (Engineering Mechanics, 1983), and, Ph.D. (Materials Engineering Science, 1992) Virginia Polytechnic. "Her dissertation involved the development of an experimental method to measure thermal stresses in bimaterial joints. She has taught courses including Experimental Stress Analysis, Engineering Mechanics, Mechanics of Materials (Strength of Materials), Strength of Materials Testing. From 1999 to 2006 Dr. Wood has been an assistant professor in the Mechanical Engineering Department at Clemson University in Clemson, South Carolina. Before moving to Clemson she spent three years as a postdoctoral research associate in the Department of Engineering Science and Mechanics at Virginia Tech. Dr. Wood is currently writing a book with Morgan Reynolds on the physical evidence explaining the events on 9/11. One of Dr. Wood’s research interests is biomimicry, or applying the mechanical structures of biological materials to engineering design using engineering materials. Other recent research has investigated the deformation behavior of materials and structures with complex geometries and complex material properties, such as fiber-reinforced composite materials and biological materials. Dr. Wood is an expert in the use of moiré interferometry, a full-field optical method that is used in stress analysis. Dr. Wood has over 60 technical publications in refereed journals, conference proceedings, and edited monographs and special technical reports. Dr. Wood started to question the events of 9/11 on that same day when what she saw and heard on television was contradictory and appeared to violate the laws of physics. Since that day she has used her knowledge of engineering mechanics to prove that the collapse of the World Trade Center twin towers could not have happened as the American public was told. "
