Advisory Group

Professor Zane Andrews

President of HNNA
Department of Physiology | Biomedicine Discovery Institute | Monash University | Australia

Zane Andrews is a Professor at Monash University in the Department of Physiology and the Deputy Head of the Metabolism, Diabetes, and Obesity Program at the Monash Biomedicine Discovery Institute. He is the Deputy Editor at Endocrinology and a Senior Editor at the Journal of Neuroendocrinology. He received his PhD in New Zealand at the University of Otago in 2003 and is currently a National Health Medical Research Council Senior Research Fellow.
Professor Andrews uses mouse and viral genetic techniques to study how food or the lack of food affects behaviour and peripheral metabolism. He is primarily interested in understanding the neural circuits that sense hunger or hypoglycemia and influence metabolism, mood and motivation. His group uses modern neuroscience techniques such as in vivo calcium imaging, optogenetics and chemo-genetics to probe the physiological and behavioural function of neural circuits. His group focuses on the hormone ghrelin as a key hormonal signal of hunger and AgRP neurons as key hunger-sensing neurons in the brain and his research over a number of years shows that hunger influences peripheral metabolism as well as many non-food associated behaviours such as anxiety and neuroprotection.

Dr Sarah Lockie

Department of Physiology | Biomedicine Discovery Institute | Monash University | Australia

Sarah Lockie’s broad background is in metabolic homeostasis regulation in mice, and includes work focusing on neural control of feeding, ghrelin resistance in obesity, efficacy and side effects of antiobesity drugs, central control of brown adipose tissue thermogenesis, and reward pathway control of feeding and motivation. Her current research interests are focused on loss of appetite in conditions such as cancer cachexia, and severe food avoidance, and how hunger-regulating circuits interact with higher order brain areas to control functions such as memory, motivation and mood-related behaviours. She heads the Appetite and Behavioural Control Group within the Metabolism, Diabetes and Obesity theme in the Monash Biomedicine Discovery Institute

Professor Dave Grattan

Past President
Department of Anatomy | School of Biomedical Sciences | University of Otago, New Zealand

Prof Dave Grattan is the Director of the Centre for Neuroendocrinology at the University of Otago in New Zealand.  His research has a particular focus on the pituitary hormone prolactin and its role in the maternal brain during pregnancy and lactation. From 2009-2014 he was the Editor-in-Chief of the Journal of Neuroendocrinology, and is currently an Associate Editor for Endocrinology. He was elected chair of the FASEB Meeting on Growth Hormone/Prolactin family for the 2021 meeting.

Dr Leigh Walker

The Florey Institute of Neuroscience and Mental Health, University of Melbourne, Australia

Dr Leigh Walker is an early career researcher at the Florey Institute of Neuroscience and Mental Health. Leigh completed her undergraduate and Hons at Victoria University of Wellington and PhD in neuroscience at the University of Melbourne. Her current research examines the neurocircuitry and neurobiology underpinning anxiety and alcohol use disorders, with a focus on sex differences.

Professor Herbert Herzog

Garvan Institute of Medical Research | Faculty of Medicine | UNSW | Australia

Prof Herbert Herzog is the Chair in Neuroendocrinology at the Garvan Institute in Sydney. He studied Chemistry, switching to Biochemistry for his PhD, which he obtained from the University of Innsbruck (Austria) in 1989.
In 1991, Herbert joined the Garvan Institute where he studies the role of NPY and other family members like PYY and pancreatic polypeptide, investigating the numerous different functions of these important molecules. Prof Herzog currently holds a National Health and Medical Research Council – Senior Principal Research Fellowship.

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 this changes with age.


Dr Chris Coyle

Department of Physiology | School of Biomedical Sciences | University of Otago, New Zealand

I’m Chris, I currently work at the University of Otago, within the Centre for Neuroendocrinology and Dept of Physiology as a Postdoctoral Research Fellow in Associate Professor Rebecca Campbell’s lab. My research focuses on the dissecting the role of androgen receptor signalling in the hypothalamus and its implications in the pathophysiology of polycystic ovary syndrome using transgenic tools and preclinical animal models. 

Dr Joe Yip

Centre for Neuroendocrinology | University of Otago, New Zealand

Dr Joe Yip is a Research Fellow at the Centre for Neuroendocrinology, University of Otago, New Zealand. His research focuses on the neuronal plasticity induced by reproductive hormones, and how this contributes to reproductive function. Specifically, he is interested in the understanding the hypothalamic tuberoinfundibular dopaminergic (TIDA) neurons in controlling prolactin secretion. This involves investigation of the mechanism underlying the plasticity of TIDA neurons’ morphology, neurochemistry, intracellular signaling and behaviour, specifically how they change their function to allow elevated prolactin levels critical for lactation.

Associate Professor Rebecca Campbelll

Department of Physiology | School of Biomedical Sciences | University of Otago, New Zealand

Rebecca Campbell is an Associate Professor at the University of Otago in New Zealand and the Deputy Director of the Centre for Neuroendocrinology. She is an Associate Editor for the Journal of the Endocrine Society and Senior Editor for Endocrinology and Experimental Physiology. Her research focuses on defining and understanding the neuronal network regulating gonadotropin-releasing hormone neurons and reproductive function. Using a wide range of anatomical and functional neuroscience tools in transgenic mouse models, she has revealed morphological characteristics of the GnRH neurons and their afferent network relevant to their function in health and disease. She is particularly interested in understanding androgen excess in the female brain and the neuroendocrine mechanisms that underpin the common female disorder, polycystic ovary syndrome (PCOS).

Professor Colin Brown

Department of Physiology | School of Biomedical Sciences |University of Otago, New Zealand

Our research group principally uses electrophysiology and immunohistochemistry to determine how the brain controls birth, lactation, and cardiovascular function. Our main focus is on how oxytocin and vasopressin contribute to preterm labour, high blood pressure and heart problems.

Dr Zhi Yi Ong

School of Psychology | UNSW | Australia

I am a DECRA research fellow in the School of Psychology, UNSW. I completed my PhD in biomedical science at the University of South Australia and received postdoctoral training at the University of Pennsylvania, USA. I am interested in understanding the neurobiological mechanisms of food intake control and addiction. Using multi-level approaches in rodent models, my research explores the neural circuits, neuropeptide function, gut-brain interaction, and intracellular signaling pathways that contribute to the control of feeding and addictive behaviours.
