Research and Professional Interests:
My long term goal is to understand how identical genomic sequences can be interpreted to cause distinct expression patterns and phenotypes. I am particularly interested in the regulation of epigenetic modifications that heritably alter the expression of endogenous and transgenic loci in plants. These phenomena have been shown to be key elements in the growth, development, and gene regulation of a broad range of organisms; I study them predominantly in maize.
