​​Dr. Grossi specializes in failure analysis and engineering investigations involving industrial machinery, process plant equipment, consumer products, and a wide range of vehicles and components in the rail, automotive, and mining sectors. Drawing on his expertise in a variety of industries, Dr. Grossi works with clients to address complex technical problems related to mechanical integrity and performance, product safety, recalls, and regulatory compliance. Dr. Grossi has provided expert witness testimony in the United States and internationally.

​Industrial Machinery and Process Plant Equipment
Dr. Grossi performs investigations involving machinery and equipment failures, machine safeguarding, industrial and occupational safety, and risk assessment, often in the context of injuries or fatalities. Some of the machines and products he has investigated include press brakes, dock levelers, lathes, milling machines, presses, aerial lifts, forklifts, various CNC machine tools, construction tools, escalators, elevators, and automatic doors. Dr. Grossi is experienced in investigating the mechanical performance and failure of process plant equipment, such as rotating machinery (e.g. turbines, generators, compressors, pumps), pressurized systems (e.g. pipes, pressure vessel explosions, piping components, heat exchangers, hoses), and auxiliary equipment, such as valves and couplers. As an ISO-certified vibration analyst, Dr. Grossi is qualified to establish, direct, and perform programs for condition monitoring and diagnostics of machines, process plant equipment, and industrial systems.

​Consumer Products
Dr. Grossi conducts engineering analyses of consumer products and has presented his findings to the U.S. Consumer Product Safety Commission (CPSC) in the context of product recall investigations. Specifically, Dr. Grossi has investigated a wide range of consumer products including, but not limited to, kitchen appliances (e.g. pressure cookers, blenders, coffee makers, ice cream machines, drinkware, can openers, ice makers, electric ranges), home appliances and white goods (e.g. washers, dryers, water heaters), indoor and outdoor furniture (e.g. beds, office mats, chairs, chaise lounges), lighting fixtures, toys, strollers, hoses, exercise equipment, robotic pool cleaners, air compressors, e-bikes, e-scooters, and bicycles.

​​Railroad
​Dr. Grossi conducts failure analysis, performance evaluations, and mechanical integrity assessments of railcar structures in both freight and passenger service. His investigations have included, for example, derailments, engineering analysis of truck (bogie) components (e.g. bearings, wheels, suspensions), railcar rollover events, railcars transporting hazardous materials, and hopper cars with corroded structure. Dr. Grossi also performs stress calculations using finite element analysis (FEA) and evaluates derailments, vehicle stability, and vehicle dynamics using various analysis tools, such as multibody dynamics (MBD) simulations.

​​Automotive
Dr. Grossi performs mechanical analyses of trucks, trailers, passenger vehicles, and vehicle components, including failure analysis, performance evaluations, compliance reviews, and durability testing. Some of the vehicle systems he has investigated include specific aspects of pneumatic tank trailers, flatbed trailers, hydraulic systems, internal combustion engines, electric motors, tires, wheels, brake hoses, fuel pumps, timing chain systems, and alternators. Dr. Grossi was employed at Gamma Technologies, where he analyzed the mechanical performance of several engine architectures, with a focus on vibration and bearing analysis.

​Mining
Dr. Grossi performs engineering evaluations related to the mechanical performance of heavy machinery including excavators, haul trucks, wheel loaders, and surface miners. Dr. Grossi worked at Caterpillar, where he performed design evaluation and multibody dynamics analysis of a wide range of heavy machines. Dr. Grossi is Mining Safety and Health Administration (MSHA) Part 46 trained.

​​Prior to joining Secretariat, Dr. Grossi was a Senior Managing Engineer at a large international engineering and scientific consulting firm. Dr. Grossi’s academic expertise includes dynamics and vibration, multibody dynamics analysis of rigid and flexible bodies, and nonlinear finite element analysis. His doctoral research focused on the advanced computer modeling of specific aspects of rail vehicles, railcar tanks, liquid storage tanks, trucks, and tires. Dr. Grossi often serves as instructor at the Vibration Institute, a U.S. institution accredited by the ANSI National Accreditation Board, where he teaches courses on vibration analysis of machines to industry professionals.​
