Dr Hu Zhang, Our People, Brain Health Research Centre, University of Otago, New Zealand

Hu Zhang Dr Zhang’s research is focused on preclinical studies of new anti-aging, antibiotics and central nervous system (CNS) agents using various animal models and the extrapolation of these results to humans. His research areas have included the following inter-related areas: biopharmaceutical analysis, pharmacokinetics, drug metabolism, toxicity, drug discovery and development.

Since 2005, he has collaborated with Dr Ping Liu (Anatomy) on the contribution of the arginine metabolic to age-associated cognitive decline, disease biomarker identification and its potential use for drug discovery and development. Knowledge gained from this work will contribute significantly to the basic understanding of the neurobiology of the ageing brain and may lead to a LC/MS based metabonomic biomarker discovery and the development of agmatine based therapeutics for cognitive decline in Alzheimer’s disease. They are currently funded by the New Zealand Neurological Foundation and the Health Research Council of New Zealand.
