Research Interest(s):

My research (done in collaboration with Dr. Ralph Keil, Hershey Medical Center) focuses on a gene named DEG1 that is involved in mitotic recombination in yeast (Saccharomyces cerevisiae). Using molecular biology techniques, my students and I successfully cloned this gene and developed yeast strains with diverse forms of DEG1. We are evaluating strains with DEG1 deletions, point mutations, and excess amounts of the DEG1 gene product to determine how these changes impact recombination rates, resistance to elevated temperatures, levels of RNA transcripts, and pseudouridyl synthetase activity. This analysis should provide insight into the mechanisms and pathways involved in recombination, DNA repair and genome maintenance. Student participants gain valuable experience in the scientific process, in genetic analysis, and in techniques such as PCR, restriction mapping, bacterial and yeast transformation, in vitro mutagenesis, and phenotype screening.
