I'm interested in understanding what causes variation in ageing and lifespan among people and animals
A list of my academic publications can be found here.
How does the environment drive ageing?
What an individual does - and where they do it - has a dramatic impact on their lifespan. Our experiences affect the way our bodies use energy and modify the DNA we were born with, continually changing us. I want to understand more about how an individual's environment, choices, and behaviours affect the molecular and physiological mechanisms that determine longevity.
Current research topics and collaborations:
- Rates of ageing relative to reproductive output in the Dasyurid marsupials
- Multidimensional animal performance in complex habitats
- Lifetime and sex-based variation in telomere length
- Relative performance and longevity of Dasyurid sperm
- Predicting speed choice in wild animals
I'm fascinated by the differences in physiology and behaviour between males and females of a species.
Over the years, I've studied avian migration and amphibian metamorphosis, run experiments and designed models, and done fieldwork in Australia, Patagonia, western Alaska, Canada, and the US Midwest.
