Published the first description of direct interaction of pathogen effector molecules with plant R-gene proteins.
At the DNA Plant Technology Corp (DNAP), Oakland CA, demonstrated that activation of R-gene responses can be engineered so that they provide resistance against a broad-spectrum of pathogens.
Led a research group at DNAP working to engineer broad-spectrum disease resistance in vegetable crops.
At the USDA-ARS, CPPC Research Unit, West Lafayette developed the first virus-induced gene silencing (VIGS) system for functional genomics research in hexaploid wheat.
Successfully applied the VIGS system for functional genomics analysis of a wide range of wheat and barley pathosystems.
US Patent: A transgene construct for improved resistance to Fusarium head blight in wheat and barley.
