Evolutionary and ecological genomics of yeast
Variation in the environments experienced by evolving populations shape the phenotypes that they express. My research asks the question of how evolution shapes population variation in plasticity in part by comparing the degree of plastic gene expression in populations of yeast from natural environments to that in laboratory evolved populations of yeast.
Evolution of Gene Expression
As one of the earliest accessible phenotypes in the translation of genotype to phenotype, gene expression levels give us insight into how upper level phenotypes are constructed. By studying the availability of variation in regulatory networks in both natural and lab-evolved populations, I seek to understand how natural selection and neutral drift have shaped genome-wide gene expression.
