Jonathan conducts failure analysis investigations and provides metallurgical consulting services for clients in the automotive, aerospace, construction, oil and gas, military, mining, manufacturing, power generation and forensic engineering fields. He composes root-cause failure analysis reports supported by non-destructive analyses, photographic documentation, chemical composition analyses, mechanical testing, metallographic analyses, fractographic analyses, and
SEM/EDS/FTIR/TGA/CT analyses.

His skills include macro-photography with DSLRs, component sectioning methodologies, forensic analysis protocols (laboratory and field), metallographic sample preparation, scanning electron microscope sample preparation, and macro- and micro-hardness testing. His vast array of skills also includes the operation of optical metallographs, operation of Keyence optical microscopes, operation of optical emission spectrometers, and operation of scanning
electron microscopes with energy-dispersive analysis capabilities.
