Casual part time consulting. Evaluated proposals for funding NASA missions including the assessment of the technical basis of cost estimates, mission risks including probabilities and cost and schedule impacts. Conducted and led research that used past mission performance data to support evaluating risk and cost analysis tools and methods. The results were used to evaluate the reliability of proposed costs and risk mitigation plans.

Provided cost analysis support including Program Office Estimates for Life Cycle Costs, Independent Government Cost Estimates, Cost Benefit Analyses. Developed POEs for JBC-P, CPCE, MCE and Cyber SU programs. Developed C-BA data for CPCE and MCE.

Part time work on software model documentation financial services industry.

Senior Cost Analyst, Lead Associate from 2006, Manager Space Programs since 2007. Developed function point SW cost estimate for USMC C2PC program. Developed a tailored cost estimating relationship and methodology for Johns Hopkins Applied Physics Laboratory software development. Worked on instrumentation cost analysis for the RLEP-2 mission for NASA Goddard SFC, software cost risk analysis for the GOES-R program for NOAA and TDRS for NASA Goddard SFC. Combined cost and schedule risk analysis for GSFC LDCM mission, NOAA GOES-R, and the MAVEN project at GSFC. Managed CADRe development, sensor data collection with CER development and cost risk analysis training tasks for NASA HQ. Led work on ICEs for a Venus Probe and GALAHAD missions for NASA LaRC. Performed a software cost estimate for the Navy ATTDS system. Pioneered application of copula methods and fat tailed distributions to joint cost and schedule analyses. Led JPSS ICE effort for the NOAA CFO and was a SME for proposal evaluations under the NASA SOMA EASSS activity.

Director for Advanced Systems and Quality (2004). Responsible foe SW QA and also developed market analysis and business plan for securing retail transactions on-line and in-store. Manager of Software Quality Assurance (2002-2004). Authored process for software development, established test plans and performance metrics. Directed software configuration management. As project lead for handwriting recognition and identification projects, cut costs by half and increased output resulting in successful demonstrations of handwriting recognition and identification software, developed algorithms in support of above efforts.

Designed and led development of mathematical software modules to predict financial effects of natural catastrophes. Was responsible for developing cost and schedule estimates based on requirements and high-level object designs, schedules, work plans, and executed them successfully.

Developed fuzzy logic, expert system, and neural network controls for curing composites with FTIR (Fourier Transform Infrared) spectra. Modeled metal heat treatment. Led project teams and wrote proposals.

Analyzed EM effects for defense and cicilian applications. Developed expert system for risk assessment of Peacekeeper missile operations. Developed antenna and impedance matching networks for in situ detoxification of waste dump sites. As co-principal investigator, formed research plan for UMTA.

Performed and lead requirements analysis, design analysis and tradeoff for defense C3 and civil air traffic control systems. Network architechture for a RMS. Nuclear weapon effects, EMI, TEMPEST requirements and project risk problems. Systems Engineering Disciplines Team Leader (1984). Systems Engineer (1984).
