Skills
I Am A Scientific Software Architect And Systems Integrator Trusted To Resolve Mission-Critical, Multi-Domain Challenges Across The Defense Spectrum — With A Proven Ability To Bridge The Gap Between Legacy Systems And Emerging Technologies, And A Mindset Oriented Toward Innovation, Precision, And Impact.
I Design, Integrate And Evaluate Complex Defense Systems Via Modeling, Simulation And Analysis (Ms&A) Of Those Systems, The Environments In Which They Operate, And The External Systems With Which They Interact. When Possible, I Anchor These Analyses By Comparing The Ms&A Results To Ground And Flight Test Data. My Go-To Tools For Accomplishing These Tasks Are Systems Engineering And Scientific Software Development, Although I Also Do Some Work In Human Centered Design And Innovation Leadership.
My Primary Foci Have Been Missile Defense And Electronic Warfare.
