Unravelling the role of heteroplasmy in mitochondrial adaptation. This project aims to unravel the evolutionary implications of heteroplasmy – a scenario in which multiple mitochondrial DNA genotypes exist in one individual. Recent studies indicate heteroplasmy is widespread, and can be caused by paternal transmission of mtDNA. But the effects of heteroplasmy on evolutionary processes remain unknown. Leveraging state-of-the-art methods, this project expects to generate new knowledge in the areas ....Unravelling the role of heteroplasmy in mitochondrial adaptation.

Evolutionary limits. This project aims to understand the processes that limit adaptation to rapid environmental change. Adaption to rapid environmental change determines population persistence. Species with restricted distributions may lack the genetic variation necessary to adapt to changing environments, although they represent the vast majority of biodiversity. Understanding why they lack the necessary genetic variation for adaptation is important for identifying and managing vulnerable biolo ....Evolutionary limits. This project aims to understand the processes that limit adaptation to rapid environmental change. Adaption to rapid environmental change determines population persistence. Species with restricted distributions may lack the genetic variation necessary to adapt to changing environments, although they represent the vast majority of biodiversity. Understanding why they lack the necessary genetic variation for adaptation is important for identifying and managing vulnerable biological systems. This project will empirically determine the contribution of mutations to key traits to better understand what limits evolutionary adaptation. Better prediction of extinction risk should inform conservation and biodiversity management.Read moreRead less
Adaptation by DNA download: Experimental evolution of a pangenome. This project aims to understand how microbes adapt when they can directly “download" new genes from their surrounding environment, or from other types of bacteria. Specifically, the proposed research will carry out the largest-scale measurements of the fitness effects of horizontally transferred genetic variation, to discover how each of these genes interacts with the environment, and with other genes. This project is expected to ....Adaptation by DNA download: Experimental evolution of a pangenome.

This project will take an inter-disciplinary approach, involving experimental evolution, an ecological framework, the measurement of organismal physiologies, and fruit fly genetics. The outcomes could change how biologists view the mitochondria, reveal mitochondria’s role in adaptation to climatic stress, and their contribution to shaping evolutionary trade-offs and conflict between the sexes.Read moreRead less
The oxygen paradox and the evolution of sex differences. Free radicals are reactive molecules linked to the onset of ageing, cancers and infertility. By advancing an emerging paradigm that contends that 'free radicals' are important drivers of evolutionary change, this project will lead the field and provide an excellent platform on which to train students to the highest standards.
Mitochondria, maternal inheritance and the evolution of male life-histories. This project aims to unravel the extent to which maternal inheritance of the mitochondrial DNA renders it susceptible to accumulating mutations that are harmful only to males; an evolutionary theory called ‘Mother’s Curse’. Left unchecked, Mother’s Curse could threaten the long-term viability of populations. This project will combine experimental techniques in ecology, fruit fly genetics and a platform for measuring phy ....Mitochondria, maternal inheritance and the evolution of male life-histories. This project aims to unravel the extent to which maternal inheritance of the mitochondrial DNA renders it susceptible to accumulating mutations that are harmful only to males; an evolutionary theory called ‘Mother’s Curse’. Left unchecked, Mother’s Curse could threaten the long-term viability of populations. This project will combine experimental techniques in ecology, fruit fly genetics and a platform for measuring physiological phenotypes to test three hypotheses central to the theory. By testing these hypotheses, the project intends to understand the causes of sex differences in physiology, longevity and reproductive health, and improve awareness of evolutionary concepts that may ultimately affect human health.Read moreRead less
