Exploring Biology with Imagination

 

RESEARCH OverVIEW

The true understanding of the biological system requires knowledge about exactly when, where, and how particular molecule functions within a cell or organ. In the past, biological studies have discovered numerous genes that regulate different biological processes. However, significant gaps still exist between these “molecular parts” and the static “phenotype” due to the lack of spatiotemporal information. Our lab uses model organisms, primarily Drosophila melanogaster, to quantitatively study the spatiotemporal dynamics of biological signals and their significance under both physiological and pathological conditions.

Current Projects

Stem Cell Biology
Stem cells play central roles in tissue regeneration and tumorigenesis. We use fly intestinal stem cells as a model system to understand the molecular mechanisms of how stem cells perceive and process both endogenous and exogenous signals.

Visualize the Dynamics
"One picture is worth a thousand words," then how about a video? New live-imaging techniques allow us to explore the unknown dynamics of various molecules in the ever-changing biological systems.
Learn more
Organ Morphogenesis
How cells form organs with completely different shapes is a fascinating question that continues puzzling developmental biologists. Now we combine molecular genetics and live imaging to dissect the mechanisms during morphogenesis.

Synthetic Biology
“What I cannot create, I do not understand.” We engineer synthetic molecules that allow people to replace, probe, and control complex biological system in vivo in order to truly understand the fundamental logic of the natural machine.
