Expertise DescriptionI have over 40 years experience in Human Factors and Ergonomics. My expertise includes physics and human factors psychology to: vehicle accidents, Americans with Disabilities Act (ADA), industrial and construction accidents, perception and vision, warnings and instruction labels, product and equipment errors, medical equipment errors, skip and fall, ergonomics and workplace layout, physics and optics. I have conducted R&D in instructional system development, perception, vehicle driving, human-computer interaction, equipment design and evaluation, and physiological processes. My research includes an evaluation of a system to prevent drunk driving, an investigation of factors contributing to decreased alertness during driving, quality engineering, studies of camouflage, and programs requiring the design of operator interfaces. I develop manuals and multimedia training programs for industrial operations, health and safety, and maintenance for light to heavy industry. I have more than 30 years expert witness experience with consultations, deposition, and courtroom testimony.
Areas of Expertise
My expert witness experience includes: product and equipment design induced errors; medical equipment errors; perception and vision; instruction and procedures; warnings and labels; vehicle accidents and reconstruction; industrial and construction accidents; slip and fall; ergonomics and workplace layout; work procedures.
My consulting service include: hazard and job analysis; safety training programs; industrial training programs; mockups; simulations; Standards of development; operations and maintenance manual development; product design.
As a vision expert, many accidents I have investigated involved lighting and glare issues. My education in physics equips me to understand the conditions that produce glare and methods to reduce it. My combined education in vision and physics allows me to address discomfort versus disability glare.
My prior experience involves the development of hundreds of hours of operations, maintenance, and safety training programs. I am experienced in labels and warnings.
I recently finished a suit against a lanyard manufacturer for improper design of the equipment. The analysis involved comparison to other major harness manufacturers and the instructions and labeling for the equipment.
Human factors issues in construction sites and municipal repair sites are well within my expertise. Additionally, my expertise includes conspicuity, lighting issues and of course, signage. It may be of interest that I served as a quality manager on a major construction site.
I am able to testify as to whether the equipment met the recommendations and standards as set forth by CPSC and ASTM. I am a member of the home playground equipment committee of ASTM and am familiar with the various standards that are in effect for this equipment. If the equipment was not assembled in accordance with manufacturer directions, I am also expert in manuals and warning. I currently am working on a different case in which a child fell from monkey bars and sustained an injury.
Although conveyor belt accidents are not in my area of expertise, cases usually benefit from two areas of expertise. First, a mechanical engineer should inspect the equipment to determine flaws in design, materials, and construction. My physics education is helpful to understand the engineer’s analysis. Second, a human factors specialist like myself should evaluate how the equipment was intended to be used, what guarding and warnings/ instructions were in place, and what the user actually did and why. Often the human factors analysis can be initially accomplished from the engineer’s analysis and photographs.
