Research Interests

My research focuses on understanding how specific neurons and neural circuits regulate systemic aging. We recently identified a role of a small population of dopaminergic neurons in regulating longevity in fruit fly. Characterization of the aging-related dopaminergic circuits holds the key to understanding how brain orchestrates aging and lifespan control.

In addition to studying the link between the high-order brain circuits and aging, I am also interested in the cellular degradation pathways that promote cellular homeostasis. Malfunction in the clearance mechanisms contributes to a range of human diseases including neural developmental and neurodegenerative disorders. Our recent studies demonstrated that, Mask, a putative scaffolding protein with RNA binding capacity, regulates lysosome function and autophagic activity. Overexpressing Mask in specific neurons is beneficial to aging and neurodegeneration. Future studies will focus on unravelling the conserved mechanisms through which Mask confers beneficial effects in post mitotic neurons.
