Research statement: 

My research is focused on chromatin remodeling and regulation of gene expression in eukaryotes. My time is currently divided among three major areas, including 1) DNA sequencing and Genotyping for members of the Wright State community through the Center for Genomics Research; 2) Identification of small molecule inhibitors for an unusual type of histone deacetylase from pathogenic microbes (malaria, toxoplasmosis, and cryptosporidiosis), and 3) in collaboration with Dr. Hostetler, understanding nuclear hormone receptors that respond to nutrients to alter gene expression
