Age-related increases in neural noise degrade information transfer in the brain and lead to diminished cognitive function. Yet with cognitive reserve, some people are able to maintain healthy functioning well into their later years. This project aims to investigate the effects of neural noise on brain connectivity, cognitive performance and reserve, advancing breakthrough work on the neural physiology of healthy cognitive ageing and malleability of neural noise.

This project aims to examine how differences in the response of males and females to pathogen attack can influence the evolution of infectious disease. This project expects to generate new knowledge in the area of host-pathogen co-evolution, by integrating approaches from the fields of evolutionary genetics, sexual selection, and epidemiology. Expected outcomes include an enhanced capacity to build interdisciplinary collaborations and development of theory that predicts infection dynamics in any species with separate sexes. This is expected to provide significant benefits, such as improving our knowledge of why the sexes differ and potentially providing new avenues for understanding disease outbreaks and preventing population declines or extinctions.Read moreRead less
