Our lab studies how interactions between cells instruct morphogenetic events such as gastrulation, tubulogenesis, and organogenesis. Using C. elegans as a model system, we combine genetic and imaging approaches to watch morphogenetic events as they unfold during development and identify the molecular mechanisms that promote them. Current projects in the lab address how cells polarize based on contact with other cells, how cells form intracellular tubes by hollowing out their cytoplasm, and how interactions between primordial germ cells and niche cells regulate early germ line development.
