Additional Information

I am a mechanical engineer specializing in the design and forensic failure analysis of HVAC, refrigeration, plumbing/piping, and fire suppression systems. I have experience designing the mechanical systems of healthcare facilities, educational facilities, industrial/manufacturing facilities, office buildings and Federal Government projects. Additionally, I spent time as a facilities engineer, evaluating existing mechanical systems, and providing recommendations as to maintenance, repair, and system upgrades. My forensic engineering experience includes investigating construction defects, mechanical equipment failures, and complex system failures involving chillers, boilers, turbines, solar-thermal systems, heating and chilled water systems, and building automation controls. I have provided expert testimony in deposition and at trial in state and federal courts of law. I have also worked as a product development engineer designing archery equipment. I have consulted in numerous product liability lawsuits concerning shooting sports injuries involving archery bows, crossbows, and firearms. I have also consulted as an expert witness / POSITA in patent infringement matters involving archery, HVAC, and construction products. I have assisted attorney clients by providing technical analysis and opinion in patent validity challenges. I have experience evaluating prior art patents, claim charts, claim constructions, declarations, as well as other extrinsic and intrinsic evidence. I have provided expert witness testimony in deposition and during multiple inter partes review (IPR) proceedings.
