I study the genetic and physiological mechanisms underlying the evolution of life history traits, with a particular emphasis on lifespan and aging. How do life history traits evolve, within and among species, to generate phenotypic variation? What are the mechanisms underlying life history plasticity and trade-offs? One central focus of my research is on understanding how hormonal signaling pathways (e.g., insulin, juvenile hormone, and ecdysone) affect the phenotypic expression and evolution of aging and trade-offs between reproduction and lifespan, immune function, and somatic maintenance. Another focus of my work is on understanding the genetic basis of evolutionary changes in lifespan and other life history traits in natural and laboratory populations. To address these problems I combine the tools of evolutionary genetics, quantitative genetics, experimental evolution and artificial selection, molecular genetics, physiology and genomics in the fruit fly (Drosophila melanogaster) and closely related species.
