Fundamental studies of the effects of rapid and repetitive finger movements and prolonged static postures on development of musculoskeletal disorders among computer users. Development of non-invasive exposure assessement tools for evaluating physiological changes, i.e. muscle fatigue, such that the chance of developing musculoskeletal injuries is reduced. Our objective is to advance the knowledge of ergonomics and human factors through field and laboratory studies with the goal improving products, tools and workplaces.

Recent Investigations

• 2011 Gender differences in keystroke durations
• 2011 Validation of a Software Program for Measuring Fatigue-Related Changes in Keystroke Durations

Fundamental studies of the effects of multi-axial vibration and shocks on comfort, exposure, and development of low back pain among diverse work populations. Development of techniques for evaluating seating and vehicle design studies in a field setting utilizing access to professional drivers and heavy equipment operators provided by our partners in industry. Our goal is to advance the science of whole-body vibration in a real world setting while evaluating exposure across a variety of exposure scenarios.

Recent Investigations

• 2010 Semi-truck drivers vibration canceling seat exposure assessment
• 2010 Transit dus drivers bus design comparison
• 2009 Snow removal loader operators traction chains exposure assessment
• 2009 Flat-bed truck drivers cab design exposure study
• 2008 Forklift operators mechanical and air-ride seat comparison
• 2007 Transit bus drivers comparison of three seats

Evaluation of posture, fatigue, performance, and preference metrics associated with the use of various, commercially available computer input devices in order to provide data-driven design recommendations to advance the feild of computer ergonomics.
