Range of experience includes thermal hydraulic analysis, structural analysis, mechanical design, regulatory compliance, fire protection, capital improvement projects, and project risk management and anlaysis. Managed over $2.5M of engineering resources with a peak management responsibility of over 28 engineers simultaneously for a national lab. Work entailed safety basis updates, capital improvement conceptual designs, engineering software upgrades, peer reviews, and long term capital improvement planning.Performed mechanical design, design reviews, and testing for prototype medical products. Listed as co-inventor on patents for a medical device. Performed thermal and structural analysis in support of the first planned landing of the Joint Strike Fighter on a Navy amphibious war ship. Analysis resulted in the recommendation of replacement of key fire protection equipment and design of shielding for other equipment. Acted as lead analyst when interfacing with the Navy on topics of thermal loading, instrumentation, and shipboard testing.Designed and participated in testing of shipboard eductors to determine root cause failure of a ship system. Work resulted in changing eductor designs which performed satisfactorily on shipboard testing.Analyzed water hammer events for commercial nuclear power plants in response to GL 96-06 using MPR proprietary software. Analysis resulted in continued operation of the nuclear power plant without the necessity of shutting down and venting injection systems.Performed a pilot project at a commercial nuclear power plant to determine margin of the class 1E electrical system (safety related) where discrepancies were discovered and corrected prior to NRC discovery.
