Biography
I gained my BSc in Zoology and Marine Biology from Jame Cook University. I then undertook my honour's degree in immunopathophysiology at the School of Tropical Veterinary Science also at James Cook University. I was awarded my PhD from the University of Queensland investigating the interplay among endocrinolgy, environment and ecology in sea turtles, freshwater crocodiles and cane toads. After two post-docs, including a millennium post-doctoral fellowship with the Zoological Society of San Diego, where I commenced working on the ecology and conservation of Komodo dragons- a research theme I continue to date. In 2006, I took a posistion as conservation ecologist with Zoos Victoria working on in situ and ex situ conservation programs. In 2009, I took up a lectureship in integrative ecology at the University of Melbourne. In 2015, I took up my current posistion at Deakin University.
Dr Tim Jessop is an integrative ecologist who studies the effects of environmental, ecological and anthropogenic disturbances on animal physiology, ecology and evolutionary biology. His primary research goal is to understand how disturbance processes act on the fitness of individuals to shape population and even community dynamics. He is also interested in assessing the effectiveness of environmental managment actions for improving biodiversity outcomes.

Teaching interests
I have broad teaching experience through my University employment at both the undergraduate and post-graduate level. Throughout my career I have taught into different subjects including Comparative Physiology, Human Physiology, Animal Structure and Function, Australian Wildlife Studies, Applied Ecology and Animal Behaviour, Seminars in Ecology and Evolution and various field zoology units.
Units taught
SLE355 Zoological Field Studies
Knowledge areas
Ecophysiology, Terrestrial Ecology, Applied Ecology, Island Biology
Professional activities
I serve as a scientific advisor to the Indonesian NGO Komodo Survival Program.
I serve as a member to scientific advisory committee for the Department of Environment, Land, Water and Planning that assists with providing adice on the listing of species under the Flora and Fauna Guarantee Act
Projects
I research across multiple projects that assess how native animals respond to the impacts of environmental, ecological and anthropogenic disturbances. These projects vary in scope and address these issues using different techniques that range from desk top modelling exercises to long running field-based studies.
My current projects include:
1. Komodo dragon ecology, evolution, and conservation. I undertake field studies to aid conservation and understanding of one of the world’s most iconic animals.
2. Macroecology and Macrophysiology: I conduct global scale analyses addressing how animal respond to ecological and environmental phenomena.
3. Predictive Ecology: Here I address how animals respond to natural and global change-related environmental variation using predictive biophysical models.
4. Functional Ecology: Developing functional monitoring frameworks to assess the impacts of disturbance on biodiversity.
5. Evaluating the consequences of environmental management actions for Australian biodiversity.
