Dave Nadeau is a principal scientist at the San Diego Supercomputer Center (SDSC), a national research center specializing in computational science and engineering, located on the campus of the University of California, San Diego (UCSD). Specializing in scientific visualization and virtual reality, he is the author of technical papers and articles on 3D graphics and VRML and is a co-author of two books on VRML (The VRML Sourcebook and The VRML 2.0 Sourcebook, published by John Wiley & Sons). He is the founder and lead librarian for The VRML Repository and The Java3D Repository, principal Web sites for information on VRML, Java3D, and related software.

Dave has taught VRML at multiple conferences including SIGGRAPH 96-97, WebNet 96-97, VRML 97-98, WMC/SCS 98, Eurographics 97, and Visualization 97. He was a co-chair for the VRML Behavior Workshop in October 1995, the first workshop on VRML behavior technology, and a co-chair for the VRML 95 conference in December 1995, the first conference on VRML. He was on the program committees for VRML 97 and VRML 98 and is SDSC's representative to the VRML Consortium.

Dave holds a B.S. in Aerospace Engineering from the University of Colorado, Boulder, an M.S. in Mechanical Engineering from Purdue University, and is in the PhD program in Electrical and Computer Engineering at the University of California, San Diego.
