The Townsend lab integrates theory, computation, and experiment to study functional genomics and evolutionary biology. Ongoing experimental research includes work characterizing genome-wide gene expression variation in the model microbes Saccharomyces cerevisiae (the wine and bread yeast) and Neurospora crassa (the filamentous fireburn saprobe). Theoretical work includes modeling of the evolution of gene expression, bioinformatics and statistics for the analysis of DNA microarrays, phylogenetics and evolutionary biology, and novel theoretical approaches for the analysis of microbial communities when horizontal gene transfer belies traditional species concepts.
