In July 2010, I completed the Doctoral Program in Cognition and Perception at NYU. My advisor was Laurence T. Maloney. Read below for a brief description of our work.

I am now a postdoctoral researcher at the laboratory of Matthias Bethge at the Max Planck Institute for Biological Cybernetics in Tübingen, Germany. My current research topic is natural image statistics.

Here is a copy of my CV (last updated August 2010).

Review Article: Maloney, L. T., Gerhard, H. E., Boyaci, H. & Doerschner, K. (2010), Surface color perception and light field estimation in 3D scenes. In Harris, L. & Jenkins, M. [Eds], Vision in 3D environments. Cambridge, UK: Cambridge University Press, pp. 65-88. [pdf]

Nearly every moment in our waking lives, our perceptual systems are bombarded with a massive amount of information about the environment. Somehow, the brain filters and processes all this input nearly instantaneously, giving us a rich experience of all the objects and surfaces surrounding us and the ability to move about and interact with the world as we please. My goal as a researcher is to improve the current understanding of these remarkable processes.

The first part of my doctoral dissertation focused on the problem of object property perception in three-dimensional environments, in which the interaction between lights and surfaces can be highly complex, generating ambiguous light signals as input to the visual system. Nonetheless, we can reliably estimate illumination and object properties separately. Our evaluation of this ability in 3D scenes is published in two articles (above banners) in the same special topics issue on light and material perception in 3D scenes.

I am also interested in the motor system. As an undergraduate, I worked in Ted Wright and Charlie Chubb's Lab at UC Irvine, where I studied how visual information about object shape is used to guide grasping movements. The second part of my doctoral dissertation was work done in collaboration with Uta Wolfe concerning how people learn their performance ability when placed in novel motor configurations.
