Utilized analysis and modeling & simulation techniques to enact policy decisions:Supported the Defense Logistics Agency (DLA) in the implementation of a new inventory level setting methodology that has reduced inventory by over $340 million since January, 2013 while maintaining customer service. ●Trained four employees on data processing procedures. ●Aided DLA in troubleshooting implementation issues within their enterprise resource planning system. ●Automated the levels implementation process with C++, SQL, and python scripts that reduced the quarterly levels updating process by over 100 man-hours.Managed a team of 8 to create a hierarchically integrated suite of models to optimally utilize UASs (Unmanned Aircraft Systems) in wildfire-locating missions: ●Created an integer program that answers where and how many UASs to locate. ●Created an agent-based model to assess mission success rates. ●Integrated the integer program and agent-based model with LMI’s SysLinksTM ●Co-authored a paper to be presented at the 2013 Winter Simulation Conference with findingsCoded and implemented expenditure models into the Rayleigh Analyzer®, a tool developed by LMI to analyze funding expenditures. ●Evaluated the funding data of more than 160 weapon systems, and analyzed the model based on eight of the weapon systems to gauge its effectiveness. ●Tested and altered the models by evaluating contracts that were deemed to be acceptable or unacceptable by the client. ●Aided in briefing project findings to the client.Analyzed item-level demand data for Air Force reparable items by modifying depletion rate table calculators and retention models. Created a tool that calculates the difference between the cost to dispose of an item and the cost to retain it.Analyzed item-level contingency retention stocks (CRS) and overall stock levels between 2004 and 2009 and recommended policy changes to reduce CRS that were implemented by the department of defense.

Performed an array of research and analysis support by running simulations, writing database queries, and creating VBA programs.●Established a baseline for studying improvements for economic retention by reviewing current economic policy, principles, and practices. Determined policy change recommendations based on a storage analysis of economic retention stocks.●Developed an integer program for determining stock location points for the National Veterinary Stockpile that were implemented by the Department of Agriculture.
