Research Topic:                                                                            

ALS is an invariably-fatal disease affecting motor neurons of the brain and spinal cord.  Greater than 97% of ALS cases are marked by the cytoplasmic mis-localization of the RNA-binding protein, TDP-43. This mis-localization, and potentially aggregation, is considered a toxic gain-of-function and clearance of this toxic cytoplasmic species could potentially be a valuable therapeutic target. Therefore, my research focuses on characterizing a novel mechanism of cytoplasmic TDP-43 clearance that seems to heavily rely on the endocytosis machinery. Elucidation of this mechanism of TDP-43 clearance will give us a greater understanding of how cellular toxicity is conferred in ALS and provide novel therapeutic targets.
