Background

Tjerk obtained his BSc (Hons) and MSc in Human Movement Sciences at the University of Groningen, the Netherlands. After graduation, he was successful in his application to begin a fully-funded PhD at the University Medical Center Groningen, the Netherlands. His PhD research evaluated the clinical relevance and neural mechanisms of unilateral resistance training with augmented sensory feedback in healthy and diseased individuals.

Tjerk is currently investigating how vision loss affects the performance of everyday activities. He regularly presents his work at national and international conferences and is an invited reviewer for various journals in human physiology and sports medicine.

Tjerk is interested in the underlying neurophysiological and biomechanical mechanisms of motor performance in healthy and diseased individuals. His current research focuses on how individuals with vision loss perform everyday activities. He captures human movements with the VICON system, measures gaze behaviour using an eye-tracker, and examines balance using a force plate. Combining these three measures provide insight in the underlying mechanism of why individuals with vision loss experience more difficulty in performing everyday tasks and why they fall more often.
