Biography
Dr. Hong XU is currently an assistant professor of Psychology in the School of Humanities and Social Sciences since 2009. She received her Bachelor's degree in Psychology from Peking University, Master and Ph.D degrees in Statistics and Psychology from University of Chicago respectively. Her research interests include study visual perception in human and non-human primates; human-computer interaction and computational modeling the neural network from vision to decision and action.
Research Interests
Dr. Hong XU's area of expertise is in vision perception. Her research interest is to study visual perception by psychophysical experiments and electrophysiological/neural imaging studies; and further model the neural network system with recorded neural activities. In particular, she is working on the following questions:

1.Visual Perception
How do we visually perceive daily objects and activities (e.g. faces and motion) and how is the visual perception affected by our previous visual experience (adaptation and 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 process in neural network? How is visual information transferred from low level to high levels? How does the feedback system work synergistically?
