Research Interest:

Multi-sensory Integration; Perceptual Learning; Adaptation

Research in our laboratory is concerned with the question of how the brain integrates the information from different sensory modalities into one coherent percept. We are interested in the question of multisensory integration from various aspects: how different sensory modalities interact; what brain mechanisms are involved, and what computational principles and mechanisms govern the interactions. We probe these questions using behavioral and neuroimaing studies in humans, as well as mathematical modeling. Other topics of interest in our laboratory are perceptual learning, and adaptation.
