RESEARCH INTERESTS

I aim to understand the neuromechanical mechanisms underlying gait and balance, their recovery in face of perturbation and our ability to quickly adjust these to environmental demands. Specifically, I'm interested in pro- and reactive movement corrections in lower limbs in hope of reducing falls in old age. To this aim, my PhD project investigated the role of response inhibition in obstacle avoidance and adjustments of tripping responses, while my postdoctoral projects primarily focus on investigating balance in novel environments and the interaction of balance with voluntary movements.


In the long term I hope this better understanding of the biomechanical and neural control mechanisms underlying proactive and reactive whole body movements improves mobility and reduces falls, especially in vulnerable populations such as elderly and patients.
