Dr. Hertzberg is the Director of Exponent’s Mechanical Engineering Center. He has extensive experience solving complex technical problems in a variety of industries including consumer products, medical devices, industrial equipment and systems, and technology product development. He often works with companies addressing the technical aspects of product recalls as well as interacting with the Consumer Product Safety Commission (CPSC). His consumer product work includes targeted testing and analysis of new products before they are introduced into the marketplace, management of product and process changes during the course of production, use of risk methodologies, substantiation of product performance claims, failure analysis of field-returned products, consumer product recall related investigations, evaluation of proposed correction action plans (CAP) as part of the consumer product recall process, and product liability. Specifically, Dr. Hertzberg has led recall related investigations for a wide range of products including: children and infant toys, child care products, strollers, sporting equipment, videogame accessories, gas and water valves, ladders, various kitchen appliances, furniture and seating products, air purification units, water coolers, fans, lighting fixtures and handheld lighters, battery operated and plug-in consumer electronics, air compressors, footwear, holiday lighting and decorative products, candles and scented products, automobile accessories, food contamination (associated with foreign materials), food and product dispensers, and medical diagnostic equipment. Dr. Hertzberg performs failure analysis investigations and addresses issues related to the mechanical behavior and degradation of materials including metal, polymer, and welded components. He has expertise in the areas of materials characterization, fatigue, fracture, corrosion, stress corrosion cracking (SCC), hydrogen embrittlement, and creep. He also has a strong background in mobile computing with extensive experience with handheld/wireless device technologies and substantiation of claims, having served as the Director of Competitive Analysis and Strategy for Palm, Inc.
