Professor Mark Walterfang graduated in medicine from University of Queensland with honours in 1993, and completed his Fellowship of the Royal Australian and New Zealand College of Psychiatrists in 2000. He has worked since this time as a consultant neuropsychiatrist at the unit, with an interest in Huntington’s disease, frontotemporal dementia, Parkinson’s disease, and rare neurodegenerative disorders including neurometabolic disorders and the leukodystrophies. Professor Walterfang has also been involved in the development of a number of clinical tools for use in psychiatric patients in the areas of cognition and behavioural observation, particularly the NUCOG (www.nucog.com.au) . In 2010 he completed his PhD in the neuroimaging of white matter in psychiatric disorders, for which he won both the Dean’s Prize and the Chancellor’s Prize for thesis excellence at the University of Melbourne. In 2023 he completed a DMedSci in biomarkers in neurometabolic disorders. His continuing research involves the neuroimaging and neuropsychiatric investigation of neurometabolic disorders including phenylketonuria and Niemann-Pick disease type C, and in shape analysis of cortical and subcortical regions in neurodegenerative disorders. He has published over 2200 Medline-indexed scientific papers, and recently contributed a new chapter on the Neuropsychiatry of Neurometabolic and Neuroendocrine Disorders to the world's most respected reference text in psychiatry, Kaplan and Sadock's "Comprehensive Textbook of Psychiatry”.
