As a key contributor to numerous industry initiatives and technologies, I have presented tutorials and workshops for the integration of Web3D media into concept, workflow, sharing, and publication.
Technical or marketing coursewares from Introductory to Advanced.

Current Research:
3D Information Displays, Interactions, and Architectures


I am investigating cognitive approaches to interactive visualization in virtual environments. Specifically, I am interested in perception and information design for embedding and coordinating multiple information types inside 3D environments. Recent work highlights the use and advantages of open standards such as XML and X3D for "Information-Rich Virtual Environments". In conjunction with Virginia Bioinformatics Institute, we are applying our research to the visualization of immune system simulations and the further improvement of softwares and international standards.
