Research Emphasis:

Fungal – Plant Interactions
My research program centers on fundamental aspects of fungal-plant interactions. From the fungal side the focus involves the identification of genes that regulate pathogenic development and signal communication. I am also the PI on a grant for the recently completed genomic sequence of Sclerotinia sclerotiorum. My other interest is in plant programmed cell death (apoptosis) and the extent to which parallels exist between plant and animal systems. We have recently shown that modulation of cell death can be an effective means to control certain diseases as well as abiotic stress. The overall goals of these studies are understanding the mechanisms that regulate plant apoptosis and implementing intervention or alternative strategies to generate transgenic plants with novel mechanisms of pathogen resistance and stress tolerance.
