Research Summary:

Complex, molecular-level interactions between plants and pathogens ultimately determine the extent to which disease develops.  Research in my lab takes systems-based approaches to characterize molecular mechanisms underlying diseases of crop species.   In general, our research addresses the following fundamental questions:

• How is pathogenesis regulated in fungi and what are the links between diverse components
of pathogenesis, e.g., morphological differentiation, conidiation, and secondary metabolism?
• What are the environmental cues that trigger pathogenesis in fungi and how are they
• To what extent is the genetic regulation of pathogenesis conserved among fungal
• How do plants respond to pathogens at the molecular level and what genes are involved?

We blend a wide range of techniques and approaches in our research, including conventional and molecular genetics, functional, comparative, and evolutionary genomics, analytical chemistry, and metabolomics to explore the basis of both fungal pathogenesis and host resistance.  Areas of particular interest include kernel-rotting diseases caused by mycotoxigenic fungi, such as Aspergillus flavus, Fusarium verticillioides, and Fusarium graminearum; foliar diseases caused by species of Cercospora, including C. zeae-maydis and C. kikuchii; and diseases caused by necrotrophic fungi, such as Botrytis cinerea.
