My scientific interests focus on the regulation of gene function; in particular, I am interested in how factors such as packaging of DNA into chromatin and organization of genes within genomes may affect gene expression in eukaryotic organisms. Students in my lab are currently engaged in a comparative genomics project that uses in silico (computer-based) analysis to annotate genes in Drosophila species, a collaborative effort of the Genomics Education Partnership (thegep.org). Past and future projects include studying the role of chromatin structure and other epigenetic mechanisms in the model plant Arabidopsis thaliana.
