Professor Deschênes is a past Director of the Thomas More Honors Program.
Dr. Deschênes’ research interests focus on delineating the role of DNA mismatch repair (MMR) in protecting cells against DNA damage induced by environmental mutagens. MMR is an essential DNA repair system used by almost all species to maintain low baseline levels of mutations arising from natural biological processes inside cells. Bacteria are an excellent model system for mutagenesis studies; excellent assays already exist for detecting mutations and measuring their frequencies, and their MMR functions have been extensively characterized. One mutagen of interest in Dr. Deschenes’ lab is the processed meat preservative sodium nitrite. Other areas of interest include exploring how MMR and other DNA repair pathways protect local aquatic bacterial and/or invertebrate populations from DNA damage induced by environmental pollutants such as metals.
