Dr Christiane Stehmann

Coordinator of the Australian National CJD Registry

Christiane is the coordinator of the Australian National CJD Registry, responsible for the day to day operations of the group and its interactions with clinicians and patient families.

Professor Colin Masters

Florey Institute and the University of Melbourne
Director, Australian National CJD Registry (ANCJDR)

Colin Masters is a Professor of Dementia Research at The Florey, University of Melbourne and a consultant at the Royal Melbourne Hospital. Colin Masters has focused his career on research in Alzheimer’s disease and other neurodegenerative diseases, including Creutzfeldt-Jakob disease.

Over the last 40 years, his work is widely acknowledged as having had a major influence on Alzheimer’s disease research worldwide, particularly the collaborative studies conducted with Konrad Beyreuther in which they discovered the proteolytic neuronal origin of the A? amyloid protein, which causes Alzheimer’s disease. This work has led to the continued development of diagnostics and therapeutic strategies and has been recognised by the receipt of many international awards.

More recently, he has focused on describing the natural history of Alzheimer’s disease as a necessary preparatory step for disease-modifying therapies.

Professor Brian Appleby

Director, National Prion Disease Pathology Surveillance Center
Professor, Departments of Neurology, Psychiatry, & Pathology, Case Western Reserve University, USA

Dr. Appleby is a neuropsychiatrist with clinical and research interests in prion diseases (e.g., Creutzfeldt-Jakob disease) and young-onset dementias.

Dr. Appleby received a B.A. in biology and philosophy from Goucher College and a M.D. from Georgetown University School of Medicine. He completed an internship at Georgetown University Hospital and a psychiatry residency at The Johns Hopkins Hospital, where he also completed a geriatric psychiatry fellowship.

Dr Victoria Lewis

Head, Molecular Diagnostics, ANCJDR

Vicki has had a keen interest in prion diseases since 2000, when she got her first job as a research assistant (RA) for the ANCJDR. As an RA Vicki ran various diagnostic tests and collaborative research projects, and it was during this time that she decided to undertake a PhD in prion research. Under the supervision of Steve Collins, Vicki Lawson and Andrew Hill, Vicki’s PhD focused on understanding the nature of infectious prion species and prion disease susceptibility. Since completing her PhD, Vicki has continued her prion research, overseas and in Australia, with interests in prion protein proteolytic cleavage, and the relevance of these events to normal prion protein function and prion diseases, presenting her research findings at various national and international conferences.

Vicki has been the recipient of an NHMRC Fellowship and University of Melbourne Early Career Researcher Grant, and has been fortunate enough to receive several CJDSGN Memorial Awards/Grants.

Vicki is currently a part-time Research Fellow in the Department of Medicine, (RMH) at the University of Melbourne, and has also returned to where it all started, working part-time for the ANCJDR, again involved in aspects of diagnostic testing and collaborative research. Over the couple of decades Vicki has made significant contributions to prion research, in particular to the areas of prion disease epidemiology and diagnostics, prion strain pathogenesis and prion protein proteolysis.
