Specific experience is described below (starting with most recent experience).

USMC Joint Simulation System (JSIMS), 1997-2001: Performed systems analysis and software requirements specification for USMC requirements for JSIMS in the areas of Combat Service Support, Nuclear/Biological/Chemical Warfare, Combat Engineering, After Action Review, Amphibious Operations, and Fire Support.

MTWS, 1989-1996: Performed requirements analysis, developing system and software specifications from user needs statements for the ground combat, movement, and ship-to-shore operations functional capabilities of the system. Identified system design architectural alternatives for evaluation. Reviewed system and software specifications and design products. Provided technical guidance on software and test design approaches. Analyzed and evaluated new technologies and prepared proposals for application of new technology in the project. Performed detailed software design and coding for the Battle Damage Assessment model. The software was developed in Ada.

From 1985-1989, served as system engineer for development of the Tactical Warfare Simulation, Evaluation, and Analysis System (TWSEAS) Integrated Maneuver Control (IMC). Developed the system design concept for a distributed user workstation architecture. Developed mathematical algorithms for representation of ground combat operations, direct fire casualty and damage assessment, and movement functions. Generated requirements specifications and software design documents. The software was developed in CMS-2Y.

From 1980-1986, worked on a variety of projects, including:
- Designed and implemented a simulation of the Navy Tactical Data System (NTDS) data link network providing data communications for an afloat battle group. The purpose of the model was to provide an analysis tool for quantifying battle group responsiveness in a high-volume threat environment. The model was developed in Simscript.
- Developed the program plan, wrote the requirements specification, and developed the initial software design for the Afloat Correlation Research System (ACRS). The system was designed to be used in a testbed environment to evaluate alternative processing architectures for proposed Afloat Correlation System functions. The development was performed in Fortran in a VAX/VMS environment, with high-speed computational algorithms performed on a Goodyear Aerospace Corporation CP-1469 Associative Processor (ASPRO).
- Performed analysis and initial design of a combat intelligence system based on knowledge engineering techniques.
- Developed enhancements to the fielded TWSEAS Map Maneuver Control (MMC) system. Designed and implemented new models for ground combat operations, barrier and sensor field detections, air reconnaissance, and casualty/damage assessments due to air-to-surface ordnance, indirect fire ordnance, direct fire engagements, and minefields. The software was developed in CMS-2.
- Performed analysis of the capabilities of tactical VHF radios to support high-speed digital communications in an urban environment.
- Developed standards and procedures for conducting Signal Susceptibility and Vulnerability assessments.
- Developed design specifications for a computer-assisted trainer for the Poseidon Communications Improvement Program.
- Conducted a survey of the use of artificial intelligence techniques in the diagnosis of faults for maintenance of avionics systems.
- Analyzed alternative submarine command, control, and communications procedures and equipment using a large-scale, interactive, warfare gaming system.

While employed at the Naval Ocean Systems Center from 1974 to 1980, performed systems analysis and software development for several Marine Corps and Navy command, control, and communications projects, including:
- Designed and implemented the ground combat and casualty/damage assessment models for the first Marine Corps staff-level warfare gaming system, the Tactical Exercise Simulation and Evaluation (TESE, later to be called TWSEAS).
- Worked in the Advanced Command and Control Architectural Testbed (ACCAT), performing analysis of new computer technologies to evaluate potential benefit to Navy command and control requirements. Analyses included evaluation of several database management systems, a natural language query system, and expert systems. Performed software development in Lisp and Rule-Interactive Transaction Agent (RITA).
- Provided simulation database and gaming support in the conduct of communications analyses for the Communications in Direct Support project, involving setup and conduct of computer simulations and analysis of simulation outputs.
- Designed and developed simulation models to analyze communications networks and command and control systems, including the Unit Level Message Switch (ULMS) packet-switching network, the Marine Integrated Fire and Air Support System (MIFASS), and the Tactical Combat Operations (TCO) ground maneuver command and control system. Also developed a model of alternative approaches for distribution of key variables in a secure digital network. These models were developed in Simscript and the Extended Computer System Simulator (ECSS).
