JONESBORO – An Arkansas State University microbiology professor has been awarded a federal grant to conduct extensive research into oral health.

Robert Shields, assistant professor of microbiology in the department of biological sciences and principal investigator for the grant, will guide a team of faculty members, doctoral degree candidates, student researchers and lab professionals who will delve into the intricate molecular mechanisms underlying tooth decay pathogens.

Molecular microbiologist Lisa McLellan of Purdue University-Fort Wayne will also be part of the research team.

“In this study, we will investigate the movement of genetic information between bacteria, a process that spreads antibiotic resistance and fuels pathogen evolution,” Shields said. “We will focus our studies on understanding this process in the oral cavity and determining the role it plays in assisting in the development of tooth decay.”

The $1.77 million grant over a five-year period will support the work of the research team and provide a supply of chemical reagents, travel expenses to present results at scholarly conferences and other expenses associated with their work.

The grant comes from the National Institute of Dental and Craniofacial Research, a division of the National Institutes of Health.
