neural development • dendrite morphogenesis • glial cell differentiation • membrane transport proteins • neuron-glial interactions • axon guidance • neurological disorders • sleep-wake regulation
We study neurons and glial cells, two major cell types in the brain. Interactions between them are vital for the central nervous system (CNS) to develop and function properly. In addition, signaling between neurons requires formation of complex intercellular connections through the patterned development of axons and dendrites. Research themes in my lab currently focus on molecular and cellular mechanisms controlling 1) differentiation of glial cells during development, 2) dendrite morphogenesis, and 3) movement and bioavailability of ions and neuroactive chemical messengers in the brain. We study how these mechanisms influence motor and sensory behaviours and sleep-wake cycles. We believe that improved understanding of these mechanisms can determine how perturbations of these processes contribute to certain neurological diseases, and can be used to promote repair in the injured or diseased CNS.
