 Research Interests:

I am interesting in using mathematical models and computer simulations to elucidate the general principles of neural information processing, and meanwhile, developing brain-inspired computational algorithms. The projects include: the interactive principle of visual information processing, canonic network models of neural information representation, computational roles of short-term synaptic plasticity, multisensory information processing, and models for neuromorphic computing.
