My students and I use molecular genetic, chemical, and biological approaches to study the biosynthesis and significance of a group of fungal toxins called ergot alkaloids. Ergot alkaloids are important in agriculture, where they contaminate pasture grasses, and in medicine, where they serve as the bases for pharmaceuticals used to treat dementia, migraines, and other issues. We study how ergot alkaloids are made by using genetic manipulations and chemical analyses to understand the roles of individual genes and reconstruct pathways.  We also study why the alkaloids are made by comparing the genetic mutants we construct to their alkaloid-producing parent strains in various biological assays. Our research has resulted in modification of the ergot alkaloid content of fungi associated with pasture grasses and engineering of model fungi to produce pharmaceutically important chemicals.
