HARUN KARIMPUR

Scientist & VR Enthusiast

@ Justus Liebig University Giessen, Germany

In the field of Cognitive Neuroscience, my primary research interests fall within the areas of Spatial Coding and the interactions between Perception & Action. I try to answer these questions by using a multi-methodological approach involving Virtual Reality, Psychophysics and Mathematical Modeling.

I am a fellow of the German Academic Scholarship Foundation,

member of the Center for Mind, Brain, & Behavior (CMBB) and

associated member of the International Research Training Group (IRTG) 1901 "The Brain in Action"

SPATIAL CODING

I'm interested in solving complex problems related to how the brain computes and represents spatial information facilitating our actions in reach space or navigation. I am working on questions like:

  • Which perceptual mechanisms influence our actions in space?

  • How do different frames of reference interact?

  • How can landmarks facilitate spatial orientation and object interaction?

EMBODIMENT

Our senses provide us with information that, once integrated, can lead to fascinating phenomena such as embodiment. In a current project, I aim to understand the underlying factors that make up this sense of one's own body. VR allows us to trick the senses and maintain a high degree of experimental control. I use a holistic approach in which I combine objective measures such as electrodermal activity and movement kinematics.

INTUITIVE PHYSICS

"This floor is quite slippery!"
In our everyday lives, we rarely need formulas to get an estimate of physical properties in our environment. In some cases, our predictions fail. But why is that the case? Why do we integrate unreliable cues? In a recent project, I started to look into this issue.
