Researcher biography

Dr Narayan is Senior Lecturer of Animal Science in the School of Agriculture and Food Sciences. Edward graduated with PhD degree in Biology from the University of the South Pacific and pioneered non-invasive reproductive and stress endocrinology tools for amphibians - the novel development and validation of non-invasive enzyme immunoassays for the evaluation of reproductive hormonal cycle and stress hormone responses to environmental stressors. Dr Narayan was also recipient of Gold Medal Award for undergraduate Bachelor of Science degree from USP.

For post-doc Edward joined Griffith University, Queensland with a successful Vice-Chancellor's postdoctoral fellowship. Edward initiated an innovative long-term research program based on the Conservation Physiology of wildlife. Edward's dynamic career research platform is based on the thematic areas of comparative vertebrate physiology, stress endocrinology, reproductive endocrinology, animal health and welfare, and conservation biology.

Edward's research team comprising of supervised Honours, Masters and PhD students (and numerous student volunteers) have made significant new discoveries, including understanding the sub-clinical physiological impacts of the debilitating pathogenic disease (chytridiomycosis) on amphibians; the physiological impacts and fitness consequences of acute and chronic environmental stressors on amphibians.

Edward has also developed non-invasive stress hormone monitoring tools for marsupials such as the Koala, Woylie and the endangered Greater Bilby. Edward has also studied the stress physiology, health and welfare of Tigers in Australian and Indian Zoos.

He has extensive postdoctoral research fellowship training in institutions spanning 4 countries (New Zealand-Landcare Research), Australia (Griffith University), India (Australian Academy of Science Early Career Fellowship – University of Pune) and Canada (Department of Biomedical Sciences, University of Saskatchewan).

Edward has supervised 40 undergraduate special topics, Honours, Masters and PhD students in Australia and from overseas.

Edward has published over 80 peer-reviewed research in collaboration with researchers in Australia such as Murdoch University, University of Melbourne, Macquarie Uni, Deakin Uni and Griffith University, and internationally (USA, India, Canada and New Zealand). Edward also has active on-going research collaborations internationally (e.g. India, Argentina, Vietnam, Canada, Brazil, and USA).

Edward also provides consultation support based on Animal Welfare related work. He currently holds membership in the Endocrine Society of Australia, International Association of Stress Physiologists, Society for Experimental Biology, Australia & New Zealand Society for Comparative Physiology and Biochemistry and International Society for Wildlife Endocrinology.

Prior to joining the University of Queensland, Edward has been an academic faculty member at Charles Sturt University (School of Animal and Veterinary Sciences) and Western Sydney University (School of Science).

Dr Narayan leads the Stress Lab (Comparative Physiology and Endocrinology) at the Gatton campus and QAAFI.
