He has applied engineering principles in the areas of accident reconstruction, injury potential/causation analyses, human factors analyses and medical device evaluation/design. As a forensic engineer, Expert 3266 has reconstructed accidents involving automobiles, motorcycles, pedestrians, amusement park rides, walking surfaces, public transportation, and railroad/industrial equipment. Expert 3266 has performed analyses to determine damage consistency between vehicles, the order of impacts in multi-vehicle collisions and to determine the driver of vehicles involved in roll-over collisions, as well as other accident reconstruction related analyses. As a biomechanical engineer, he is qualified to use injury based evidence from medical records, photographs and autopsy reports to create a complete and quality analysis. Expert 3266 is a seasoned professional and has testified over 65 times.

Over the course of his career, Expert 3266 has worked in the area of orthopedic biomechanics, developing equipment related to the testing of implantable orthopedic medical devices, studying human kinematics, and testing the material properties of human tissue. Expert 3266 understands occupant dynamics/kinematics and can reconstruct an occupant’s motions during an accident. He is familiar with head injury causation, spinal biomechanics and the biomechanical properties of human tissue including muscle and bone. He understands environmental factors that may contribute to an incident including human factors.

Expert 3266 is also an accomplished medical device engineer and has experience in the field of neuroelectrical engineering. As a clinical engineer, Expert 3266 worked in the field to advance the science of neuromodulation, or the application of electricity to a group of nerve fibers to reach a therapeutic result. Expert 3266 comprehends neuroscience principles and the generation/cessation of action potentials with the aid of an applied electrical signal. He has worked closely with research and development departments to advance the design of tools and implantable devices used in the operating room and clinic. He has contributed to the content and design of study protocols used in clinical trials to evaluate the safety and efficacy of medical devices. He has trained surgeon investigators as well as clinical sales teams on the implantation of these devices. Expert 3266 is familiar with Investigational Device Exemption (IDE) and Pre-Market Approval (PMA) processes.

Currently, Expert 3266 spends most of his professional time reconstructing accidents and performing biomechanical analyses. He is a reviewer for an independent institutional review board. He specializes in evaluating medical device study protocols for their scientific merit and safety prior to being performed on human subjects. With the growing emphasis being placed on human factors, Expert 3266 also spends time helping companies design usability studies and designing usability into studies for medical device manufacturers seeking FDA approval.


Principal Engineer
Private Firm, Houston, Texas

Expert 3266 provides expert engineering analyses in cases involving motor vehicle collisions, injury causation, industrial/railroad accidents, amusement park ride accidents, product liability and premises liability. He performs complex analyses to determine the effects of occupant restraint systems, the driver of a vehicle, and other occupant related analyses. Expert 3266 evaluates medical devices and equipment for failures and malfunctions. He is currently a medical device consultant for an independent institutional review board to determine the merit and safety of device oriented clinical trials. Expert 3266 also provides human factors engineering services for cases involved in litigation and the design of usability studies for medical device companies.

Senior Field Clinical Engineer
Private Company, Minneapolis, Minnesota

Expert 3266 provided biomedical engineering support to surgeons during the implantation of the MAESTRO system, a fully implantable class III neuromodulation device intended for the treatment of obesity. As a human factors engineer, Expert 3266 invented a patent pending device to assess patient compliance prior to enrollment in the Empower clinical trial. The device was responsible for the second largest number of patent exclusions after BMI. He was responsible for the design and implementation of surgeon and clinician training sessions which included laparoscopic implantation in porcine specimens. As a liaison between R&D and the surgeon investigators, Expert 3266 facilitated the transfer of clinical and engineering information.
