The Taylor Lab's current projects involve evolution of two species of a genus of human pathogenic fungi, Coccidioides, evolution of a model fungus, Neurospora, and the diversity of fungi that decay the bioenergy crops Miscanthus and sugarcane. They are initiating two additional studies about the diversity of fungi, one on those that populate indoor environments, and another about those associated with the roots of pine trees throughout North America.
Recently published work involves phylogenomics of Ascomycota fungi and adaptation by gene family expansion and contraction, population genomics and adaptation by introgression and selection of Neurospora crassa, and female mate choice and the evolution of reinforced reproductive barriers in Neurospora.
Future work will focus on population genomics of ecotmycorrhizal fungi and population genomics of Neurospora discreta in western North America.

In a demonstration of “reverse-ecology,” UC Berkeley biologists have shown that one can determine an organism’s adaptive traits by looking first at its genome and checking for variations across a population. The study offers a powerful new tool in evolutionary genetics research, one that could be used to help monitor the effects of climate change and habitat destruction.
