Jay's major research interests are occupational ergonomics and biomechanics. He is particularly interested in developing and evaluating evidence-based interventions to reduce physical exposures to reduce occupational injuries and illness and therefore improve workers' health and well-being. Jay is currently studying how the reduced exposure to whole-body vibration (WBV) affect the musculoskeletal health outcomes and disability. He is also interested in optimizing the human's interaction with mobile devices, virtual reality (VR), and augmented reality (AR).
Jay is the Principle Investigator of five externally-funded research projects:
1) “Systematic Evaluation of Multi-axial Suspension to Reduce Whole Body Vibration Exposures in Heavy Equipment Mining Vehicle Operators” to determine the efficacy of different engineering controls (mining vehicle seat suspensions) in reducing the multi-axial WBV exposures in mining vehicles and the associated biomechanical loading on the musculoskeletal system;
2) "Evaluating the Effects of Multi-axial Whole Body Vibration Exposure on Postural Stability in Mining Equipment Vehicle Operators" to determine whether the effects of mining vehicle's WBV exposures on postural balance and fall-relate injury risks are different between vertical-dominant and multi-axial WBV exposures.
3) "Effects of Whole Body Vibration Exposure on Physiological Stresses in Mining Heavy Equipment Vehicle Operators" to quantify the relative impacts of different types of WBV exposures (vertical dominant vs. multi-axial WBV) on physiological stress.
4) “Evaluation of Biomechanical Exposures in the Neck and Upper Extremities During Augmented Reality Interactions” to characterize biomechanical exposures, comfort, and usability during augmented reality interaction.
5) "Physical and Cognitive Impact of Virtual and Augmented Reality Interactions" to objectively quantify and compare biomechanical stress in neck and shoulder and cognitive brain function (executive function and working memory) during Virtual and Augmented Reality.
He is also a co-investigator of NIOSH-funded research project: “Randomized Controlled Trial of Whole Body Vibration in Truck Driver” to determine whether substantially reducing WBV exposures has an effect on low back pain outcomes.
