| Born out of Liberty Mutual’s commitment to help people live safer, more secure lives, the Liberty Mutual Research Institute for Safety has helped to improve the occupational safety and health of millions of workers for more than 50 years. Through laboratory and field-based investigations, the Research Institute seeks to advance scientific, business-relevant knowledge in workplace and highway safety, and work disability. Research findings are shared with the worldwide health and safety community through peer-reviewed journals and conference presentations. Ultimately, these findings are used to develop recommendations, guidelines, and interventions that help reduce risk and control costs.
To achieve its mission, the Research Institute comprises four Centers:
- Center for Physical Ergonomics - studies the causes and mechanisms of occupational injuries with a focus on musculoskeletal disorders.
- Center for Disability Research - investigates worker disability and ways to achieve safe and sustained return-to-work for injured or disabled workers.
- Center for Injury Epidemiology - conducts original epidemiological research into risk factors for occupational injury and studies the burden of workplace injury.
- Center for Behavioral Sciences - studies the impact of behavioral, cognitive, and organizational factors surrounding workplace injuries and highway collisions.
