Dr. Amber L. Southwell, Assistant Professor, Burnett School of Biomedical Sciences, Division of Neuroscience, has been working in preclinical therapy development for Huntington disease (HD) since 2002. In 2009 she earned her PhD at the California Institute of Technology working with Dr. Paul Patterson to develop an intrabody gene therapy for HD. From 2009-2016, she did postdoctoral research at the University of British Columbia with Dr. Michael Hayden where she developed several novel mouse models of HD, a selective mutant huntingtin gene silencing therapy, and a CSF biomarker for brain huntingtin. She began her laboratory research group at UCF in January 2017, where she continues these studies while also applying her successful strategies for HD to other inherited neurological diseases.
