Montana Tech Research Thrust: Computation & Modeling Systems

Roger Jensen joined the Montana Tech faculty in 1999. He teaches courses in occupational risk reduction, safety laboratory, law and ethics for OSH, and fire protection. Prior to his current position, he had 30 years of experience in occupational safety and health. Since joining Montana Tech, Dr. Jensen’s research focuses on student research projects suitable for senior projects and masters’ theses. Students have performed and published studies on attributes of warning signs, attributes of risk-reduction matrices, and measurement systems for assessing stairway uniformity. In addition to student-focused research, Dr. Jensen has worked to elevate occupational safety from a rule-based occupation to a more science-based profession. 

From 1992 to 1999, Dr. Jensen consulted in occupational ergonomics and safety as an employee of a technical services company named UES, Inc. In 1991, he was a visiting lecturer at the University of New South Wales in Australia. Earlier in his career (1969–1991) he was a commissioned officer in the U. S. Public Health Service assigned to the National Institute for Occupational Safety and Health where he conducted applied research in occupational heat stress, injury epidemiology, and safety research. Dr. Jensen used what he learned in these positions to write a book entitled Risk-reduction Methods for Occupational Safety and Health, published by Wiley Press in 2012 (second edition in 2019). It provides an overview of the many risk-reduction methods used by professionals in occupational safety, ergonomics, and industrial hygiene.

Research Interests

Dr. Jensen’s recent research has been on the design of risk-assessment matrices. These are measurement-like tools for the occupational safety community to use for anticipating effects of changes in safety resulting from new risk-reduction tactics. These are in the form of a table with columns from differing levels of severity, the rows are categories of likelihood, and the cells contain indicators of risk. Traditionally, the design of these matrices has been a committee-based approach. Dr. Jensen advocates for a more objective, systematic approach through conducting experiments; two recent experiments have been completed and published. 

A second area of interest involves modeling processes and factors leading to occupational injuries and fatalities. He provided a graphic model of the accident sequence that accounts for events before, during, and after the injury event. Dr. Jensen describes the approach in a book and teaches students the model.  

Research Expertise

Dr. Jensen has developed expertise and research skills through his graduate studies and work experience. ​

  • Conducting studies of occupational heat stress.​
  • Planning and conducting safety research developed while assigned to the NIOSH Division of Safety Research, 1977-1991. ​
  • Developing epidemiology skills while Chief of the NIOSH Accident and Injury Epidemiology Branch (1977-1984). Research methods used included: retrospective analyses of workers’ compensation claim data, including back injuries, repeated motion wrist disorders, heat and cold exposure caused claims, fatalities in agriculture, and fall from vehicle injuries and fatalities. ​
  • Developing prospective epidemiological studies: (1) an observational study to learn how thermal workplace conditions affect safety-related behavior, (2) an interventional study to determine if safety training leads to improved safety at work, and (3) effects of introducing person-handling equipment in a nursing home. These studies were contracted out.
