Director of the Hunter Cancer Biobank

Marjorie Walker

Marjorie Walker is Professor of Anatomical Pathology at the University of Newcastle Australia, an Honorary Staff Specialist at NSW Health Pathology, John Hunter Hospital Campus, NSW and Director of the Hunter Cancer Biobank, HMRI Newcastle. Previously she was Reader and Honorary Consultant at the Centre for Pathology, Faculty of Medicine, Imperial College London, until 2012.Her expertise as a histopathologist is in interpretation of clinical or molecular events in tissue sections, correlating both routine pathology and immunocytochemistry to demonstrate particular cells or their function or secretion with clinical patient data. I principally work in gastrointestinal and urological pathology. In cancer research I have interpreted the clinical data and immunostaining of tissue microarrays in unravelling prostate cancer pathways for example Hey1, Hey L, FUS, WNT signalling, DKK3, in androgen resistant (aggressive) tumours with the prostate cancer group at Imperial College, London, UK. At the University of Newcastle she works with Professor Hubert Hondermarck on the role of ProNGF and nerve induction in gastrointestinal, thyroid, pancreatic and breast cancers, using microarrays.  Her research in gastrointestinal pathologies in functional bowel disease, particularly functional dyspepsia is redefining these disorders as disease entities. She is a major contributor to global coeliac disease guidelines, including definitions, management and diagnosis and the transitioning of paediatric patients to adult care.
