Research Interests:

I study a rare form of human muscular dystrophy called dysferlinopathy. This disease is caused by mutations in the dysferlin gene and results in the loss of membrane repair in human skeletal muscle. We use the C. elegans worm to model the disease. These worms have a conserved homologous gene, which is also called dysferlin. Mutations in C. elegans dysferlin results in membrane fusion defects in developing sperm, ultimately causing sterility. The aim of my research is to rescue the sterility of these worms and then apply that knowledge to the human disease, with the ultimate goal of identifying a way to treat this rare form of muscular dystrophy.
