The underlying theme of my research is to further the understanding of phenotypic variation and its impact on ecological, environmental and evolutionary performance.  This research has had two different focuses: one explores the effects of anthropogenic stressors in natural populations and the second explores evolutionary genomics.  This research uses transcriptomics to quantify gene expression and relates the variation in gene expression to development, physiology and environmental stress. My laboratory combines these quantitative measures with high resolution Population Genomics to discern changes most likely evolving by natural selection. This research seeks to enhance our understanding of the genetics creating adaptive phenotypic differences and, importantly adds a stronger quantitative and statistical analysis to evolutionary biology.
