I am a post-doctoral researcher in Prof. Karl Gegenfurtner’s lab at Justus-Liebig-Universität Gießen. My research focuses on visual perception and its underlying neural mechanisms by combining psychophysics, eye-tracking, two-photon calcium imaging, and modeling.

Lights exist everywhere, but how humans perceive the brightness of real-life illuminations is less studied. To address this, I use LED lamps to measure human brightness perception and their corresponding pupillary responses.

Another question that intrigues me is how visual perception can be connected with neuronal activities. For example, how the brain discriminates different colors, how it assists us in maintaining color constancy, how it processes simple visual stimuli and higher-order complex stimuli. To study this, I apply two-photon calcium imaging to record neuronal responses in macaque monkeys.

I am also interested in brain plasticity, particularly in multi-sensory perceptual learning. Using a specific training method, I found modality specificities can be easily erased. Visual learning can improve auditory perception and also vice versa.

Interests:

• Color vision: heterochromatic brightness, lights and illuminations, color constancy
• Neural mechanism of vision
• Perceptual learning
• Auditory-visual integration
