As a population geneticist, I am interested in how genes change from one generation to the next and among contemporary populations. I have carried out research investigating each of the five evolutionary forces: selection, mutation, genetic drift, gene flow, and non-random mating. I am also interested in ecology as the arena in which evolution takes place. I work on plants because of their beauty and inherent interest as well as their many desirable attributes as study organisms. Most of my more »
As a population geneticist, I am interested in how genes change from one generation to the next and among contemporary populations. I have carried out research investigating each of the five evolutionary forces: selection, mutation, genetic drift, gene flow, and non-random mating. I am also interested in ecology as the arena in which evolution takes place. I work on plants because of their beauty and inherent interest as well as their many desirable attributes as study organisms. Most of my projects combine molecular genetic analysis with phenotypic data.
With Lynn Bohs, I am working on the phylogenetic systematics of the neotropical genus Witheringia (Solanaceae).
Areas of Expertise:
Research Interests: Evolutionary ecology, plant mating systems, seed dispersal, gene flow, colonization, range limits
