Biography

Prof Ian Chapman has a well-established track record of clinically based research relating to the endocrinology of aging and nutrition. His major research interest is currently the "anorexia of aging", with a particular focus on the gastrointestinal control of appetite and energy intake, including the role of gastrointestinal hormones. This work has been supported by three NHMRC Project Grants (currently 2010-12), a number of University of Adelaide and Royal Adelaide Hospital grants, and commercial funding (Organon, The Netherlands) - the latter to undertake an intervention study - and has been influential in raising the awareness, both nationally and internationally, of the importance of this problem, and the need for nutritional assessment and intervention where appropriate. Prof Chapman's standing in the field of nutrition in the elderly is attested to by numerous invitations to speak at national and international scientific meetings. He is a co-author of 89 refereed publications, and 12 book chapters. Subsequent to his appointment to the Royal Adelaide Hospital in 1996, Prof Chapman has supervised 8 PhD students (from science, medical, dietetic, and nursing backgrounds), 4 honours science students, 2 overseas research fellows and numerous medical students undertaking research training attachments. Two of his previous PhD students are now specialist geriatricians and an number of his previous students are continuing in clinical research in the area of nutrition.
