Prof Herbert Herzog is Conjoint Professor at UNSW Medicine & Health and a National Health and Medical Research Council of Australia Research Investigator (L3). He studied Chemistry, switching to Biochemistry for his PhD, which he obtained from the University of Innsbruck (Austria) in 1989. In 1991, Prof Herzog moved to Sydney where he studies the role of NPY and other family members like PYY and pancreatic polypeptide, investigating the numerous different functions of these molecules in various physiological settings. Prof Herzog has published his findings on NPY in over 330 articles which are cited over 27000 times. Prof Herzog’s current work focuses on determining the fundamental processes that can lead to the development of obesity, or the other extreme anorexia, especially investigating the brain's role in the regulation of eating behaviour, stress and glucose homeostasis. He is also interested in how homeostatic processes that regulate bodyweight are coordinated with other homeostatic processes in the body, like the one that control bone and fat mass and how these effects change with age.
