Vivian C. Paulun

I am a postdoctoral fellow in vision science working in Roland Fleming’s lab at the University of Gießen.
I have received a fellowship that allows me to work with Nancy Kanwisher and Josh Tenenbaum at MIT, which I hope to start soon.
I am studying how humans can visually perceive functional (material) properties of objects, such as softness or elasticity. My research combines psychophysics, computational modelling, computer simulations/graphics and 3D mesh analysis (and soon also machine learning and neuroimaging) to investigate the following questions:

  • How do we gain a meaningful and predictive understanding of our visual world at a glance?
  • How does the brain represent the physics of our surrounding world in such rich and efficient manner?
  • And how do we use such information to guide our actions?
Deriving functional properties from visual input is a computational challenge the visual system solves with surprising ease. Although the two-dimensional projection of the world on the retina is highly ambiguous, we gain a rich and meaningful percept of the world around us just by looking at things. We can identify objects and the materials they are made of; we know how they would feel to the touch and anticipate how they would respond to an applied force. Seeing the functional properties of objects is a central ability in order to successfully interact with our environment.
