Siby Samuel

Dr. Samuel directs the User Performance Lab (UPL) at the University of Waterloo. Dr. Samuel’s research broadly spans surface transportation human factors, healthcare human factors and safety. Dr. Samuel utilizes a variety of experimental techniques to measure human performance and study human behavior. The core theme of his work is centered around the etiology of crashes (or errors) or the study of crash (error) causation. The goal is to advance user safety by accounting for the limitations of both, infrastructure and interface device design. Specifically, Siby’s research deals with:
- Road User (drivers, pedestrians, bicyclists and motorcyclists) safety
- Caregiver Behavior and Medical Errors
- Autonomous vehicles, Connected vehicles and Intelligent Transportation Systems (ITS)
- Design and assessment of Traffic Control Devices, Roadway Infrastructure and Automotive Interfaces
- Application of Virtual Environments for Rehabilitation and Occupational Therapy.
- Development and evaluation of population-specific, cognitive Training Interventions (novice drivers, older drivers aged 65 and above, pedestrians, special population with ADHD and mild cognitive impairments)
- Measurement of Driver Distraction, Fatigue, Mental Workload and Situation Awareness.
