Thesis Advisor: Laura Ranum, Ph.D., Molecular, Cellular, Developmental Biology and Genetics Graduate Program

Thesis Research:

I am conducting thesis research in the laboratory of Dr. Laura Ranum. In the Ranum lab, we are interested in finding and characterizing genes that cause neuromuscular disease. Our end goal is twofold: we strive to elucidate mechanisms underlying specific neuromuscular diseases, and we also hope to advance understanding of normal brain and muscle development and function. Recently, others in the Ranum lab have shown that mutations in beta-III spectrin cause spinocerebellar ataxia type 5 (SCA5). My project involves developing a murine model of SCA5 to characterize disease pathogenesis.
