My interests are evolutionarily broad and include animals, plants and fungi. A major focus of the lab is the genomic analysis of gene expression programs during plant gene expression programs, particularly during embryogenesis and seed development, and the underlying regulatory mechanisms required for the initiation and maintenance of these programs. This work has illustrated the combinatorial interactions of cis and trans -acting factors that result in specific gene regulatory events. We are also using genomics tools to study the interaction of the rice blast fungus, Magnaporthe grisea , with plant hosts; the circadian control of gene expression; and the development of the vertebrate retina. An additional focal area is the utilization of molecular and cellular approaches for crop improvement. As part of these research activities, we have developed or adapted high throughput genomics approaches to accelerate the gene discovery process and subsequent analysis of gene expression and function.
