DR. HARUN KARIMPUR

Scientist

until Sep 21 - Postdoctoral Researcher @TAO: The Active Observer | Giessen - Cardiff - Amsterdam

In the field of Cognitive Neuroscience, I aimed to gain insights from complex data streams in human perception & action research. How do humans interact with objects in their environment? How do they navigate? And how can we overcome the limitations we are facing when trying to solve these problems? I tried to answer these questions by using a multi-methodological approach leading to experience with a wide range of tools such as Virtual Reality, Motion Capture, Psychophysics and Surveys.

I worked for European Active Observer project as a member of the Center for Mind, Brain, & Behavior (CMBB) and alumnus of the German Academic Scholarship Foundation

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 project pursued by our doctoral student Pierre-Pascal Forster, we 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. We use a holistic approach in which we 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.
