This team will be a true example of multidisciplinary research in that no one part of the team has the wide-ranging expertise needed to undertake the research alone. The program will draw upon the theoretical expertise of two major state Universities, the practical and innovative technological experience of a high-tech company, and the outcome-based expertise of a school actually deploying the products. Given all three pieces of the overall project, dramatic and effective results can be expected.
