Dr. William Wallefeld graduated from the University of Notre Dame (Fremantle) with a Bachelor of Medicine and Surgery (MBBS). He completed his advanced training in Neurology across major teaching hospitals in Western Australia before moving to Sydney to undertake a clinical research fellowship in neurogenetics, focusing on mitochondrial disease. His PhD research centred on the molecular pathobiology of inherited muscle diseases.

Currently, at NeuRA, Dr. Wallefeld sees patients with neurogenetic conditions and mitochondrial disease in the outpatient clinics. He also cares for neurogenetics inpatients admitted to Prince of Wales Hospital. His research activities include recruiting patients for the Natural History of Mitochondrial Disease study and working on a project aimed at discovering biomarkers for mitochondrial disease using mitochondrial autofluorescence in urinary specimens, in collaboration with researchers from the UNSW School of Biomedical Engineering.

Dr. Wallefeld's commitment to advancing the understanding and treatment of neurogenetic and mitochondrial diseases drives his clinical and research endeavours at NeuRA.
