Dr. Zolock's expertise in the field of engineering includes analytical and experimental evaluation of vehicle crashworthiness and occupant protection, vehicle dynamics, and mechanics. He specializes in automobile, bus, pedestrian, heavy truck, and rail vehicle accident investigation and reconstruction. 

His experience in photogrammetry, passenger vehicle and heavy truck event data recorder (EDR) download and analysis, full scale rail vehicle testing, physical testing and evaluation of the design and performance of Roll Over Protection Structures (ROPS) for off-highway recreational vehicles, and automobile crash, dolly rollover, handling testing, sled testing, and FMVSS testing enhances his consulting contributions to the reconstruction of accidents.

His work has emphasized study in the areas of materials, applied mechanics, dynamics, vibrations, finite element analysis, vehicle handling and collision simulation, biomechanics and occupant injury modeling, and component and full-scale field-testing.

Prior to joining Exponent, Dr. Zolock held the position of Mechanical Engineer at the Department of Transportation / Research and Innovative Technology Administration / Volpe National Transportation Systems Center in Cambridge, MA, for 9 years. His core work specialized in research and development projects related to railroad vehicle/track interaction, train derailment cause finding and prevention, train make-up and performance, rail vehicle suspension design and performance, rail vehicle crashworthiness, accident injury causation, and rail vehicle occupant safety and protection.

Dr. Zolock is familiar with test and/or analysis protocols used to demonstrate compliance with numerous National Highway Traffic Safety Administration (NHTSA) FMVSS Regulations, Federal Railroad Administration Regulations (FRA), American Public Transportation Association (APTA) recommended practices, and the ANSI/ROHVA standards.

While working at the Volpe Center, Dr. Zolock wrote a Ph.D. dissertation at Tufts University titled, "A Methodology for the Modeling of Forced Dynamical Systems from Time Series Measurements using Time-Delay Neural Networks." The dissertation studies the use of neural networks to predict the wheel/rail force response of rail vehicles to track geometry variation. While at Penn State University, Dr. Zolock wrote a thesis titled, "Experimental Observation and Characterization of Tire Standing Waves." At Penn State, Dr. Zolock focused classroom studies on experimental and analytical dynamics, vibrations, modal analysis, signal analysis, mechanics of materials, and composite materials. Previous work experience at Micro Motion included experimental and analytical modal analysis of coriolis based mass flow meters, high pressure feedthru testing and design, and coriolis mass flow meter design.
