Spinocerebellar ataxia type 1 (SCA1) is a dominant, fully penetrant, neurodegenerative disease characterized by progressive motor dysfunction and premature death. SCA1 pathology in the brainstem, underlying lethal aspects of the condition, is poorly understood. My research uses genetic, molecular, and computational approaches to elucidate molecular mechanisms of SCA1 in the brainstem.
