Corporate Overview (PDF)

Atmospheric Sciences

The Atmospheric Sciences staff at Exponent provides consulting services in air quality and atmospheric sciences. Our staff specializes in air quality and meteorological modeling, permitting, and licensing. We investigate accidental releases of chemicals to the atmosphere, simulate transport and fate of chemical substances, and develop measures of prevention and control, such as emergency preparedness and response. Areas of air quality modeling include: industrial plumes, dense gases, photochemical reactions, mobile sources, forest fires, explosions, radioactive releases, and odors. Our atmospheric scientists work closely with chemical engineers, combustion specialists, atmospheric modelers, and thermal and process engineers to predict and evaluate the dispersion of air emissions. We also work with Exponent’s risk assessors to evaluate health risks posed by atmospheric releases to the ambient air and to indoor environments, as well as the health effects of air pollution.


Exponent’s Biomechanics consultants use scientific and engineering principles to analyze human motion, loading, and injury potential in a variety of transportation, industrial, and recreational settings. Whether we are investigating an accident or evaluating technologies designed to mitigate injury, we offer an unparalleled combination of experience and expertise in injury analysis and research. Our biomechanical analyses involve scientific evaluation of human movement and loading during a dynamic event, and the evaluation of that movement for purposes of assessing injury mechanics and injury potential. We examine the relationships between the forces applied to the human body, the motions of the human body, and the physical and mechanical damage to structures of the body. We also examine the relationships of these forces and motions to conditions that are diagnosed by medical personnel.

Through close interaction with our colleagues that specialize in accident reconstruction and human factors, we analyze the exposure of humans to a given loading environment, including injury potential, injury mechanics, and injury mitigation. Testing, frequently conducted with crash test dummies, can be used as confirmation or demonstration of our biomechanical analysis. Using this multidisciplinary approach and adhering to the scientific method, we are able to determine how and when a documented injury occurred during an incident, or whether a claimed injury is consistent with the exposure to a certain mechanical environment.

Injury Analysis

Human Factors

Human factors is the scientific discipline concerned with the interactions of humans with products, with their environment, and within processes. As such, it applies knowledge about human capabilities and limitations to the investigation of accidents, to the mitigation of hazards, and to the design of products. Individual factors include cognition, attention, perception, memory, and decision-making; body size, strength, and dexterity; and the ability and willingness to process and react to information. Potential influences on human behavior include such factors as visibility, sound levels, and disclosures of all manner; for example, warning labels and other manufacturer-generated or -provided materials. The application of human factors spans a wide range of different and diverse industries, such as transportation (e.g., automotive, aviation, rail), medical and pharmaceutical, industrial (e.g., construction equipment, process control rooms), consumer products (e.g., electronics, child products), food, and clothing.

Exponent’s human factors staff holds Ph.D.-level degrees in a variety of disciplines including experimental psychology, cognitive neuroscience, industrial and systems engineering, and kinesiology. We have extensive experience examining issues related to human performance, user experience, and ergonomics, and we use this experience to investigate a wide array of scenarios such as automobile, motorcycle, bicycle, train/railroad, and trucking accidents; alleged medical device- or medication-related injuries; industrial and occupational accidents; injuries associated with consumer products; and trip-and-fall incidents. We also leverage this experience in the evaluation of, and consulting for, products under development; for example, in the context of FDA medical device, pharmaceutical, or cosmetic approval or clearance, or in the development of product labeling. In doing so, we utilize such methods as usability tests, label comprehension tests, analysis of large databases, hazard/risk analyses, observations, online surveys, focus groups, user interviews, eye tracking, balance testing, and others.

Occupational & Environmental Health Risk Assessment

Risk assessment is a systematic process for analyzing information on exposure and effects of toxic agents and other environmental hazards to assess the likelihood of adverse effects to health and safety of individuals and populations (i.e., health risks) potentially exposed to such agents. The process integrates information regarding whether a particular chemical is, or is not, casually linked to a particular health effect (hazard identification); the relation between the magnitude of exposure and the probability of occurrence of the health effect (dose-response or toxicity assessment); the route, duration and magnitude of exposure (exposure assessment); and the characterization of the nature and magnitude of health risk (risk characterization).

Risk assessments are used in a variety of contexts, including evaluating potential impacts of exposure to chemicals associated with consumer products, occupational settings, or specific contaminated sites, and in developing risk-based criteria to protect workers and the public. The risk assessment process is of necessity highly interdisciplinary to address complex health issues, and draws from diverse fields such as biology, chemistry, ecology, engineering, environmental sciences, industrial hygiene, mathematical modeling, medicine, public health, statistics, and toxicology.

Exponent’s Center for Occupational and Environmental Health Risk Assessment is composed of an interdisciplinary team of scientists, physicians, and engineers who have decades of experience assisting clients address and evaluate complex workplace and environmental health and safety questions. Our staff is highly knowledgeable in risk assessment methodologies and related analyses that critical components of many workplace practices and environmental regulatory decisions. Exponent’s consultants conduct site assessments to evaluate potential exposures to chemical, biological, and physical hazards in all types of media—air, water, food, and environmental surfaces. Our clients request site assessments for regulatory purposes, including compliance with OSHA regulations and California Proposition 65 reporting requirements, chemical spills or emergencies, and for litigation purposes. Our specialists in Occupational and Environmental medicine have diverse corporate and clinical backgrounds, and have specialty training in environmental and occupational medicine, as well as clinical toxicology, that allows them to provide health consultation and related support services to companies and institutions around the world. We have collectively worked on thousands of cases of possible occupational exposures, safety investigations, and compliance investigations and have a broad array of experience on projects that cover the full range of occupational settings.
