Modeling and Simulation

System integrator for the federated Human Social Cultural Behavior (HSCB) training platform for soldiers to hone negotiating skills required to derive critical terror network information from the non-combatant population. The Hybrid Irregular Warfare/Improvised Explosive Device Network-defeat Toolkit (HI²NT) federation combined the First-Person Cultural Trainer (FPCT) interactive 3D environment with the computer-generated forces of One Semi-Automated Forces (OneSAF), the HSCB simulated operational environment of the Joint Non-kinetic Effects Model (JNEM), and the Process-oriented Data Visualization (ProDV) data analytics platform.

Developed an infrastructure and essential services (IES) module that tracks and manages critical services such as water, electrical and agriculture modeling for a specific areas of operation within simulation federations.

A simulation-based environment for modeling the spread of a disease within livestock or poultry, effectiveness of potential disease response and control strategies, and the associated monetary costs. The system enables parameterization, management, distributed execution and aggregation of results, supporting "what-if" analysis and comparison of strategies by epidemiologists and responders in order to understand and assess potential disease events and their associated impacts.

A producer-friendly crop model- and sensor-based irrigation decision support system designed to provide real-time irrigation schedules and projected economic outcomes based on water use and production goals. The system uses management information from the user in conjunction with externally sourced data, including projected short-term weather, and generates crop growth and economic model scenarios. Remote detection of plant water stress using a sensor platform mounted on a pivot irrigation system improves irrigation schedules. Demonstrated with cotton in the Texas Rolling Plains region.

Developed a concept model to simulate Level 1 site exploitation of component debris following a detonation event by conventional or improvised explosives.

A system to investigate strain movement and divergence across both time and space, as well as track and compare disease history and spread across animal production systems. The system integrates sequence data from multiple sources, incorporates different sequence alignment, comparison, and tree construction tools, and provides various visualization and analysis tools for working with the data. This is one perspective of the AgConnect system.

A decision support tool for assessing supplemental heat requirements in barn depopulation during a Highly Pathogenic Avian Influenza (HPAI) outbreak.

Designed and developed a wildlife disease model for Classical Swine Fever (CSF) within feral swine to address limitations of current models, support assessment of the wildlife risk, inform strategies to prevent wildlife interaction, and simulate disease spread, potential time to detection, possible control and mitigation strategies, and the respective economic costs.
