Professor Chan is an elected Fellow of the Royal Society of Biology. He is the recipient of the First Medallion of the Australian Neuroscience Society. He also received the HKU Outstanding Researcher Award. He has a long record of commitment to education and was awarded the HKU Outstanding Research Student Supervisor Award and Medical Faculty Teaching Medal. He served as President of Hong Kong Society of Neurosciences, Chair of International Brain Research Organization (IBRO) Asian/Pacific Regional Committee, President of Federation of Asian-Oceania Neuroscience Societies (FAONS), and Standing Executive Committee Member of the Chinese Neuroscience Society. He is currently President of the Asian Pacific Society for Neurochemistry and Vice-President of The Chinese Association for Physiological Sciences. He is the Editor-in-Chief for IBRO Neuroscience Reports and Associate Editor for European Journal of Neuroscience. Professor Chan’s research interests include synaptic mechanisms underlying plastic modification of neural networks for spatial learning as well as the exploitation of pluripotent stem cell-derived glial cells and neurons in the assembly of functional neural circuits.
Neural plasticity: Circuitry development & rewiring after injury

To find the cellular and molecular regulators of plasticity in sensorimotor circuits, our studies focus on the sensitive period in postnatal development. We used novel pharmacological and genetic approaches to manipulate the sensorimotor system and monitor for cellular and molecular changes that effect behavioral outcomes.
We have revealed a postnatal period critical to the modification of vestibular circuits responsible for spatial navigation. We found that excitatory-inhibitory balance within these circuits tunes synaptic plasticity for cognitive functions. We identified neuromodulators that induce or reset experience-dependent synaptic plasticity in acquisition of spatial navigation.
With the use of animal models of neural injury, we found mechanisms to harness glial reactions in facilitating neuroregeneration. We also exploited human bone marrow stromal cells and pluripotent stem cells to derive glial cells and neurons in the assembly of functional neuronal networks, providing therapeutic benefits for post-traumatic regeneration of peripheral and central nerves.
