Florian Kadner joined the lab as a PhD student in May 2019.

Until September 2022 he was working on the DFG project “Active vision: control of eye-movements and probabilistic planning”.

Research interests

I am interested in how humans carry out eye-movements across different tasks and how this can be understood with models of probabilistic planning. To investigate these issues, I try to examine environments and stimuli that are as natural as possible. Other areas of interest are image saliency, adaptive human-computer-interaction models and applied methods of machine learning and cognitive modeling.
