Dr. Hong XU's area of expertise is in vision perception and neuroscience. She studies visual perception through a multidisplinary approach: psychophysics, electrophysiology (EEG), eye tracking, virtual reality (VR), and computational modeling. In particular, she studies face perception and self-motion heading perception and wayfinding by asking the following questions:

1.Visual Perception
How do we visually perceive objects (e.g., signage, faces) in daily activities (e.g., walking, cycling and driving) and how is the visual perception affected by our previous visual experience (e.g., adaptation and implicit learning)?

2. Human-computer interaction
What is the basis of effective design in visual displays? How does our visual system analyze large amount of data/information in a short period of time? What kind of optimization process is involved? Furthermore, what is the role of attention and eye movement in this process?

3. Computational modeling
How to model the hierarchical information processing system in neural networks? How is visual information transferred from low levels to high levels? How does the feedback system work synergistically with the feedforward system?
