Current Research

  • Defining daily, seasonal and annual changes in gene expression in conifers (the Douglas-fir Transcriptome Observatory)
  • Linking spatial genetic differentiation in Port-Orford Cedar to migration, climatic and selective pressure from pathogens.
  • Defining the recent colonization history of Yellow Cedar across SE Alaska
  • Developing genetic markers for plants and animals of management concern.

Research Interests

  • studying the genetic basis of adaptation through the integration of genomic (transcriptomic) and quantitative variation
  • studying the population and evolutionary genetic history of North American members of the pine family
  • defining mutation rates in conifers to understand their significance in adaptive processes
  • defining patterns of neutral differentiation as a foundation for understanding quantitative variation in restoration plant species.

Past Research

  • population and evolutionary genetics of wild cottons
  • gene evolution and gene expression in polyploid plant genomes
  • biochemistry of antiretroviral agents targeting immune deficiency viruses

Why This Research is Important

Genes -- the DNA codes present in all living organisms -- are the basis of adaptive traits that make species resilient to a changing climate and an array of diseases. The genes of plants are poorly understood, and this is especially true for genes that help plants adapt to changes in seasonal and annual weather. This research applies new genomics methods to address a fundamental question: What genes do plants use to sense seasonal changes in light quality, temperature, and water availability?  By defining genes that have a large impact on growth and health, we can use this information to guide breeding methods and plant selections that result in broadly adapted trees that contribute to resilient forest communities.
