Recent research:
This body of work integrates engineering, ergonomics, and measurement science to address real-world challenges across transportation, manufacturing, and machinery systems. The studies collectively examine how ergonomic and design factors influence human-centered outcomes in heavy-duty vehicle cabins, how injection-molded polymer orientation affects dimensional stability and process efficiency, how oil-condition and thermographic analyses reveal early wear and contamination in hydraulic systems, and how altitude affects internal combustion engine behavior through sensor signals and ECU adjustments. Methodologically, the research employs controlled experimental setups (simplified cabins; injection parameter variation), motion capture, EMG, and WAXS to quantify posture, muscle activity, and molecular orientation; rigorous oil-condition testing against international standards with thermography; and field-sensing data from absolute pressure and throttle sensors across varying altitudes, with ECU calibration assessments. The impact lies in providing quantitative guidance for cost-effective ergonomic improvements in low-resource settings, improving manufacturing process control and part quality, enabling better predictive maintenance and safety in machinery, and enhancing diagnostic accuracy and engine performance across varying elevations.
