Biography
Dr. Napierala received her BS in Biology and Chemistry from the University of Indianapolis in 2002. She earned her PhD degree in Biochemistry and Molecular Biology from Indiana University School of Medicine in 2007, then completed a postdoctoral fellowship in the laboratory of Dr. Sharon Dent at the University of Texas MD Anderson Cancer Center in 2012. Dr. Napierala held a faculty position at University of Alabama at Birmingham before returning to Texas to join the UT Southwestern faculty in 2022.
Research in the Napierala laboratory is entirely focused on the most commonly inherited ataxia in humans, Friedreich’s ataxia (FRDA). FRDA is a severe and progressive neurodegenerative disease caused by reduced levels of the mitochondrial protein, frataxin. Dr. Napierala’s research projects include specifying gene and protein expression patterns unique to FRDA in order to identify novel therapeutic targets and disease biomarkers; defining pathogenic mechanisms of frataxin missense mutations in FRDA; establishing a therapeutic window for frataxin expression using patient-derived induced pluripotent cell (iPSC) line models.
