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 in various industries including transportation, construction, mining, agriculture, forestry, and fishing. Jay is also interested in human-computer interactions such as Virtual Reality and Augmented Reality.
Jay is the Principle Investigator of seven 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) "Effects of Multi-axial Whole Body Vibrations on Postural Stability" is to quantify the effects of occupational WBV exposures on postural balance and fall-relate injury risks in professional vehicle operators.
5) "Improving vessel equipment: Evaluating fishermen-led safety design ideas in the Dungeness crab fleet" to complete objective biomechanical assessments to estimate injury risks on commercial crab harvesting tasks and evaluate an ergonomic intervention to reduce both fatal and non-fatal injuries in the commercial fishing industry.
6) “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.
7) "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.
