Enhanced, developed new features for, and documented a model using C & SES/Workbench (a state-of-the-art discrete modeling software) that models the HLA. The HLA model allows the users to test current and potential modeling federations by specifying the federates, or simulations, and communications systems involved. By allowing the users to parameterize their models the HLA model predicts the speed and resource demands of their model, the RTI (RunTime Infrastructure), and communications aspects of their HLA compliant models.

-Managed a team of programmers on the MCS Conversion Project to a successful completion. The MCS Conversion involved rewriting and adapting the Phoenix Synchronization Matrix to the TKC's (Tightly Knit Confederation: Mitre, CSC, et. al.) operating environment.
