Evolutionary and Physiological Genomics of Adaptive Traits.
The research in my lab is motivated by the fact that most species are subdivided into systems of finite subpopulations and that the pattern of phenotypic and genetic variation within and among populations provides crucial information about evolutionary processes. In my lab we combine these observations with modern genomic methods and ecological and evolutionary theory to address long-standing yet largely unanswered questions in evolutionary biology. These include:
- What are adaptive traits?
- What is the genetic basis of adaptive trait variation in nature?
- What is the relative importance of different evolutionary processes in shaping this variation within and among populations and species?
- How does the genomic system interact with independent variables (e.g., age or environment) to change the expression, evolution, and maintenance of genetic variation in nature?
- How do functional polymorphisms mechanistically modify biochemical and physiological processes to give rise to phenotypic variation in nature?
My research primarily focuses on Drosophila melanogaster as an evolutionary and ecological genetic model system. We use Drosophila populations (and species) because they display a rich collection of natural genetic variation in many ecologically and evolutionarily relevant phenotypes; many of which appear to exhibit strong patterns of local adaptation among populations and species.
