Research interests

Dr. Olson's research is focused on safety and health interventions for lone workers, and on behavioral self-management methods. The overreaching goal of this research is to understand how organizations can best protect and promote health among workers who are physically isolated from peers. Dr. Olson has extensive experience conducting injury prevention and health promotion research in transportation industries (aviation, bus, trucking), but also has current projects in home health care and long-term care industries.

Current projects


The Tech4Rest project is a randomized controlled trial designed for team trucker drivers. The study aims to reduce fatigue, improve sleep, and increase well-being for team drivers who have an inherently challenging sleep environment (sleeping in a moving truck). The study will assess the effectiveness of an enhanced cab intervention that utilizes a therapeutic mattress and an active suspension driving seat to alter whole body vibrations. This enhanced cab intervention will be studied on its own as well as in combination with a behavioral sleep intervention. Tech4Rest project is currently in the pilot phase.

Success & Health Impacts For Transit operators during Onboarding (SHIFT Onboard)

SHIFT Onboard stands for "Success and Health Impacts For Transit operators during Onboarding." It is enhanced training and support for new bus operators during their first year on the job. The program involves group activities and discussion during operators’ initial training period, followed by collaborative and supportive online challenges. Online challenges include setting health and job success goals, and tracking goal progress and job satisfaction, and completing short training topics on health and job success. New operators’ supervisors also receive training on how to support newcomers’ safety, health, and well-being on the job.

Safety and Health Involvement For Truck drivers (SHIFT)

The Safety and Health Involvement For Truck drivers (SHIFT) program was a weight and health promotion program tailored for commercial truck drivers. Over 450 drivers from 5 companies participated in the SHIFT program which produced medically meaningful and statistically significant weight loss. The difference between treatment and control groups in average weight change was –1.0 units of Body Mass Index (-7.3 lbs). SHIFT is currently being adapted for bus operators and will focus on the long-term prevention of weight-related health conditions while also fostering well-being, job satisfaction, and overall work performance for new employees.

Oregon Fatality Assessment and Control Evaluation (OR-FACE)

The OR-FACE program is designed to prevent occupational fatalities through surveillance, targeted investigation, assessment, and outreach associated with traumatic work-related deaths in Oregon. OR-FACE is supported by a cooperative agreement with the National Institute for Occupational Safety and Health (NIOSH) through the Occupational Public Health Program (OPHP) of the Public Health Division of the Oregon Health Authority

Community of Practice And Safety Support (COMPASS)

The Community of Practice And Safety Support (COMPASS) program is a peer-led social support group intervention designed to improve social resources, reduce the risk of injuries and promote health among caregivers. Over 140 home care workers participated in the COMPASS randomized controlled trial, which found that COMPASS made a significant positive impact on home care workers' perceived community of practice, use of ergonomic tools, safety communications and hazard correction, and healthy eating. The COMPASS project is being disseminated in Oregon in partnership with the Oregon Home Care Commission. COMPASS is currently being adapted for Personal Support Workers.
