Dr. Renee Duckworth, Ph.D. is Associate Professor of Ecology and Evolutionary Biology. The ultimate goal of her work is to understand the link between micro and macroevolutionary processes with specific focus on ecological feedbacks and evolutionary diversification. To achieve these goals, she integrates approaches from evolutionary and physiological ecology to quantitative genetic and genomic methods. Her current work uses large-scale field experiments, empirical measures of lifetime fitness and molecular multi-generational pedigree reconstruction to investigate the dynamics of trait evolution in the context of range expansion and species coexistence in passerine birds. Current projects in the lab include the evolution of adaptive introgression, the mechanisms of species coexistence at range margins, the role of adaptive maternal effects in range expansion, and the origin and evolution of animal personality traits.
