 Overview 
 overview
Dr. Zavras' research interests involve the molecular and genetic epidemiology of oral diseases with a particular emphasis in oral carcinogenesis and osteonecrosis of the jaw. Studying large populations globally, Dr. Zavras has developed methods to discover markers of genetic susceptibility and gene environment interactions and to move discoveries from the community to the bench and back to the clinic and the community.
