I am Shuchen Guan (官漱尘), a research scientist at Justus-Liebig-Universität Gießen, Germany. My research employs psychophysics (both laboratory and online), eye-tracking, virtual reality, two-photon calcium imaging, and computational modeling to investigate visual perception and its underlying neural mechanisms.

My main research interests focus on color vision, particularly heterochromatic brightness—how color information is integrated to influence brightness perception—along with color constancy, hyperspectral imaging, and melanopsin responses. Beyond chromatic processing, I study achromatic visual features such as orientation, spatial frequency, and more complex nonlinear stimuli to better understand how perception arises from neuronal activity.

I am also fascinated by the dynamics of perception, including serial dependence, which describes how recent visual experiences bias current perception, and perceptual learning, exploring how the visual and auditory systems adapt and interact through training.

Interests:

• Color vision: heterochromatic brightness, lights and illuminations, color constancy
• Serial Dependence
• Neural mechanism of vision
• Perceptual learning
• Multisensory integration
