Introduction
I am currently applying Knowledge Translation and stakeholder engagement practices as well as education research to developing motorcycle rider training strategies from recent research evidence.

Conference Paper
Full-text available
The unique dynamics of PTW trajectory control seem to blend unconsciously with human postural and steering actions. For example, the motorcycle seems to follow where the head turns. Expert riders may claim to steer solely by “looking” and “leaning” while engineers know that counter steer inputs to the steering column are required for efficient dire...
Article
Motorcycle rider steer responses to unexpected collision emergencies have not been studied experimentally. We used a motorcycle simulator with elastic steer mechanism and modified car driving model to simulate the input-output counter steering response of two-wheeled vehicles in combination with a car pop-up paradigm from driving studies to evaluat...
Article
Full-text available
Collisions with other vehicles represent the biggest threat to riders of powered-two-wheeler (PTW), and while emergency braking is the evasive manoeuvre most frequently required in PTW riding, many riders fail to perform it adequately due to constraints on response time precipitated by failures of perception, cognition and control actions. Effectiv...
Article
Background Low back pain (LBP) has been previously associated with delayed anticipatory postural adjustments (APAs) determined by trunk muscle activation. Lumbar stabilization exercise programs (LSEP) for patients with LBP may restore the trunk neuromuscular control of the lumbar spine, and normalize APAs. This exploratory study aimed at testing th...

A new research area explores the relationship between motorcycle rider muscle activation patterns and vehicle kinematics and kinetics to understand the interaction between human control inputs and vehicle kinematic outcome. A common factor in serious motorcycle accidents is the absence or inadequacy of braking by the rider to avoid collision. This...
Article
Belly dance was used to investigate control of rhythmic undulating trunk movements in humans. Activation patterns in lumbar erector spinae muscles were recorded using surface electromyography at four segmental levels spanning T10 to L4. Muscle activation patterns for movement tempos of 2 Hz, 3 Hz and as fast as possible (up to 6 Hz) were compared t...

Research shows that one of the biggest threats to powered two wheeler (PTW) riders is collision with another vehicle at or near an intersection. Our goal is to devise a method for training riders to perform better at emergency evasive maneuvers. This method must address the integration of perception and action inherent in any coordinated response t...

My doctoral research used the novel paradigm of belly dance to study control of complex trunk movements.
Project
In this project I am working in collaboration with engineers and specialists in motorcycle safety and safety system development to characterize and understand the control actions used by motorcycle and scooter riders in emergency maneuvers and regular riding tasks. On current project involves characterizing the coordination patterns and response timing in emergency braking maneuvers. More recently I have begun to investigate the differences and interaction between controlling the motorcycle's trajectory through steer inputs versus body displacement (as in hang-off), and the associated differences in muscle coordination patterns. Through these methods we hope to better understand the elegant and mostly intuitive interaction between rider and powered two-wheeled vehicle that is both the source of its attraction and increased risk compared to 4-wheeled vehicle travel.
