My research interest includes two parts: one is neuronal plasticity, the other is advanced light microscopy and image analysis.

How brain maintains its plasticity throughout life in response to changes in developmental and environment? The research in my lab is trying to dissect the cellular and molecular mechanisms governing the remodeling and plasticity of neuroendocrine cell. We use a genetic model organism, the fruit fly (Drosophila melanogaster) to study the remodeling of a group of neuroendocrine cells and the behaviors these cells control. Our research involves neurobiology, developmental biology, cell biology, molecular genetics, animal behavior, and advanced imaging.

Advanced light microscopy has become more and more important not only in life science, but also in many other science fields including material and structure science, engineering science etc. How to apply and improve advance light microscope techniques, such as fluorescent live imaging, deep tissue multi-photon imaging, FRET, FLIM, and FRAP? I have been collaborated with many labs inside and outside of university to promote research involving advanced light microscopy and image analysis.
