Researcher biography
Primary Areas of Interest: Comparative Animal Physiology, Animal Welfare and Conservation Physiology
I embarked on higher education at the University of the South Pacific, where I earned a Ph.D. in Biology. I conducted research work in non-invasive reproductive and stress endocrinology tools for amphibians, unlocking the secrets of the reproductive hormonal cycles and stress hormone responses of Fijian ground frogs.
My postdoctoral research fellowships took me to institutions across four countries: New Zealand, Australia, India, and Canada. Each destination enriched my knowledge and expertise, adding diverse dimensions to my academic repertoire. In 2010, I joined Griffith University in Queensland, Australia, where I began research on the Conservation Physiology of wildlife in collaboration with leading WIldlife Ecologists. The postdoctoral research has yielded remarkable insights into the physiological regulation of stress in amphibians and I also had opportunity to develop hormone monitoring tools for iconic Australian wildlife such as koalas. This exposure generated my passion to conduct further research on the health and welfare of koalas. Over these years, I have been lucky to work with and supervise over 20 Honours, Masters, and Ph.D. students.
My current research program seeks to bolster animal resilience through a multifaceted approach, involving physiology, behavior, and management practices.
I returned to Australia in 2015 upon completing my international postdoctoral fellowship at the University of Saskatchwen, Canada. Prior to starting Faculty appointment at UQ, I have had the worndeful opportunity to teach at regional universities including Charles Sturt University (Wagga Wagga) and Western Sydney University (Hawkesbury Campus).
I am currently based in the School of Agriculture and Food Sustainability (AGFS) as academic member of the Animal Science Discipline Group. I teach primarily Animal Physiology & Anatomy and supervise a dynamic group of research scholars through the Stress Lab. I am Category B member of the UQ Animal Ethics Committee (NEWMA). I also represent the University of Queensland as a LINK member for the Universities Federation of Animal Welfare (UFAW).
International Engagement
I have engagement through the European Union Funded ClearFarm Research which brings Animal Welfare standards to livestock products from a farm to plate approach, using Smart-Farm and Precision Ag Technologies.
UQ joins €13m project to bring technology to livestock sector
In 2023, my team of scholars from the Stress Lab organised and Chaired the 38th Australia and New Zealand Society for Comparative Physiology and Biochemistry (ANZSCPB) conference at the UQ, Gatton campus.
UQ Gatton hosts successful 38th ANZSCPB Conference
I have presented our research through Conversation Articles

What does a koala's nose know? A bit about food, and a lot about making friends
Koalas can learn to live the city life if we give them the trees and safe spaces they need
With the right help, bears can recover from the torture of bile farming
