In my research I am interested in the interaction between action and perception. The ‘actions’ I investigate are hand movements. Our hands are very important to interact with our environment: we use them all the time to manipulate objects.
The manipulation of an object starts with grasping and lifting it. This might seem easy, but if we don’t want to squeeze a fragile object such as an egg, for example, we have to scale our fingertip forces and grip to the object properties. At the same time, we receive information about these properties by getting feedback from sensors in the skin. This is very useful if we have never touched the object before as it allows us to learn how to handle it.
To investigate how hand movements and fingertip forces are planned and controlled during grasping and lifting objects of different sizes and weights, I use precise motion tracking and force sensors. Furthermore, I examine how humans adjust their movements to new sensory information or multi-sensory conflicts. I also investigate the perception of objects by using psychophysical techniques, for instance, by asking participants how large or how heavy they think objects are. By comparing these measures, I study how these perceptual and motor effects are related to each other.
In addition, I am looking at which brain areas are involved in the control of these action and perceptual systems. I use transcranial magnetic stimulation to stimulate the brain and evaluate how this affects the control of movements and the perception of objects.
I have a background in Human Movement Sciences and in psychophysics (the study of perception). After I finished my bachelor Human Movement Sciences at VU Amsterdam in the Netherlands, I continued to master Human Movement Sciences at the same university. As part of my master, I performed a research internship in at the Manchester Metropolitan University in the United Kingdom. In this project, I studied the eye–hand coordination in pointing tasks.
After graduating, I started a PhD on haptic perception at Utrecht University and continued this position after two years at the VU Amsterdam. During these four years, I investigated the haptic saliency of object properties with haptic search tasks. If a property is salient, this means it is processed very efficiently. Therefore, it can be felt very easily and quickly. In addition, I looked at the exploration movements that are made when haptically searching for object properties.
I currently work at the KU Leuven in Belgium, where I explore the relations between action and perception in grasping movements. At the Motor Control and Neuroplasticity lab, I have the opportunity to also investigate the brain areas that are important in controlling action and perception systems. Since 2017, my research is funded by an FWO post-doctoral fellowship.
Since 2017, I am a member of the junior board of the Belgian Society for Neuroscience.
