Research and Expertise

  • Research Interests
    Assessment of physical overexertion of people at work and the development of data necessary for the design of equipment, jobs, and the environment for enhancing safety, health and productivity. Specific emphasis placed on empirical laboratory and field experiments for evaluating physical strength and anthropometry for manual work. Physical overexertion areas focuses on cumulative trauma disorders and injuries.
