My lab studies the molecular genetics of development in the nematode Caenorhabditis elegans. This microscopic worm has proved a fruitful model for understanding basic biological problems. Research students in my lab are studying a gene called fax-1, which functions in development of neurons and a related gene called nhr-67, which functions in the development of various cells and organs. These studies provide models for understanding an inherited form of human blindness called Enhanced S-Cone Sensitivity and for understanding the mechanism cell-to-cell signaling and cancer.
