Adaptation in an Infinitesimal World

Nick Barton's research centers on the evolution of populations that are distributed through space, and that experience natural selection on many genes. These interests grew from field work on the narrow hybrid zones that separate divergent taxa, including grasshoppers, toads, butterflies and deer.
The mathematical methods developed for analysing these have proven useful for a wide range of problems in evolutionary genetics and beyond: speciation theory, quantitative genetics, coalescence in structured populations, and evolutionary computation.
