Research Interests
Molecular basis of neuronal development and plasticity; neurodegenerative diseases and drug discovery.

Prof. Ip’s major research focus is on signal transduction in the nervous system. In particular, she is interested in understanding the molecular signals that control the precise wiring of neuronal circuit essential for proper brain function. Her current research projects are aimed at elucidating the molecular mechanisms that underlie neuronal survival, differentiation, axon guidance, synapse development and plasticity. Research efforts are also directed at identifying novel molecular targets that are critically involved in the pathophysiology of neurodegenerative diseases, and using traditional Chinese medicine as a source to identify drug leads for neurological disorders.
