Establishing a role for specific nutrients in Drosophila dietary restriction
… starvation, has been shown to be the most robust and reproducible intervention to extend lifespan in diverse organisms ranging from yeast to mammals, including the fruit fly Drosophila. Despite over 70 years of research, primarily on rodents, the mechanisms by which DR extend lifespan in any …

Phylogenetic and developmental studies into the evolution of an insect novelty
… bodyplans. This thesis addresses the evolution of one characteristic feature of the insects: the intercalary segment of the head. This small, appendageless segment is the homologue of the ancestral crustacean second antennal segment and its evolution underlies the loss of the second …

Evolutionary analysis of mammalian genomes and associations to human disease
Statistical models of DNA sequence evolution for analysing protein-coding genes can be used to estimate rates of molecular evolution and to detect signals of natural selection. Genes that have undergone positive selection during evolution are indicative of functional adaptations that drive species …
