CURRENT RESEARCH

Understanding the worker. Improving the work.

PUBLISHED RESEARCH

Fatigue monitoring & worker trust

Published research examines how construction professionals perceive, trust, and prefer subjective, objective, and hybrid fatigue-monitoring approaches.

PUBLISHED RESEARCH

Smart-garment deployment readiness

A published multidimensional framework examines what smart-garment technologies need to progress from laboratory prototypes to sustainable deployment.

FUNDED FIELD RESEARCH

Stay Sharp, Stay Safe

The Job-Site Safety Institute-funded field-intervention project is developing low-burden, bilingual fatigue-reset tools for workers and supervisors.
