Ralph S. Baric, PhD
Dr. Ralph Baric is the William R. Kenan, Jr. Distinguished Professor in the Department of Epidemiology and Professor in the Department of Microbiology and Immunology. He has spent the past three decades as a world leader in the study of coronaviruses and is responsible for UNC-Chapel Hill’s world leadership in coronavirus research. For these past three decades, Dr. Baric has warned that the emerging coronaviruses represent a significant and ongoing global health threat, particularly because they can jump, without warning, from animals into the human population, and they tend to spread rapidly.
The Baric Lab uses coronaviruses as models to study the genetics of RNA virus transcription, replication, persistence, pathogenesis, genetics and cross-species transmission. He has used alphavirus vaccine vectors to develop novel candidate vaccines. Dr. Baric has led the world in recognizing the importance of zoonotic viruses as a potentially rich source of new emerging pathogens in humans, with detailed studies of the molecular, genetic and evolutionary mechanisms that regulate the establishment and dissemination of such a virus within a newly adopted host. Specifically, he works to decipher the complex interactions between the virion and cell surface molecules that function in the entry and cross-species transmission of positive-strand RNA viruses.

Most of the research in the Baric Lab uses coronaviruses as models to study the genetics of RNA virus transcription, replication, persistence and cross-species transmission. Dr. Baric also has used alphavirus vaccine vectors to develop novel candidate vaccines.
Zoonotic viruses represent a potentially rich source of new emerging pathogens in humans, yet little information is available concerning the molecular, genetic and evolutionary mechanisms that regulate the establishment and dissemination of such a virus within a newly adopted host. Dr. Baric's group utilizes molecular, genetic and biochemical approaches to decipher the complex interactions between the virion and cell surface molecules that function in the entry and cross-species transmission of positive-strand RNA viruses.
