Research Interests

In the Cox Laboratory, we use the soil nematode, C. elegans, as a model system for studying morphogenesis. Morphogenesis is the process by which tissues acquire three-dimensional shapes during development. In particular, we study the role of the actin regulator, tropomodulin, in regulation of intestinal development. The aim of our research is to gain new insights into the basic mechanisms of how biological tubes are built. This is important, in part, because many of our tissues and organs and built from tubes (e.g. lungs, vascular system, kidneys and glands).
