My work combines TMS and fMRI to reveal the potential applications and limitations of brain stimulation in vision research. My projects have provided critical information about where in the brain we can use brain stimulation to trigger artificial neural activation.

As the main focus of my work I study brain mechanisms of binocular disparity processing using a combined approach of TMS, fMRI and EEG: I investigate cortical mechanisms of stereovision which serve to combine the two retinal images. Specifically, I study how visual cortex uses implausible disparity information to support a robust, unambiguous depth perception of our environment. I also study how mechanisms of stereovision in non-sensory brain areas interact with the visual brain to support a coherent depth percept when disparity information is noisy.
