Dr. Ralph Baric, Professor of Epidemiology and Microbiology & Immunology, is an internationally recognized expert on Noroviruses and SARS coronavirus. His group has been interested in aspects of both host and viral genetics and how they relate to understanding pathogenesis and developing control tools. His research also focuses on identifying the molecular mechanisms governing emerging virus cross species transmission and pathogenesis in humans and seeks to identify the viral and host determinants which influence susceptibility to infectious diseases.

Dr. Cohen’s research focuses on the transmission and prevention of transmission of HIV, with emphasis on the role played by STD co-infections. In 2005, Dr. Cohen received an NIH MERIT Award for ongoing support of this work. Much of Dr. Cohen’s research has been conducted in resource constrained countries, especially in the African country of Malawi and in the People’s Republic of China. Dr. Cohen serves as the Chair of the Scientific Advisory Board of the China CIPRA (located at the China CDC), and as co-director of an NIH Ellison Fellowship Program at the National STD Center in Nanjing China.
Dr. Stephen Cole, Professor, is interested in study designs and analyses that accurately estimate parameters of central interest to population-health scientists, such as the risk.

He uses diverse statistical and spatial analytical methods are informed by theory from the fields of health geography, epidemiology, ecology, and others. These theories and methods are used to examine various topics such as the role of population-environment drivers in pathogen evolution, how social connectivity contributes to disease incidence, and using environmental indicators to predict disease outbreaks.

The major focus of his laboratory is the molecular epidemiology of vector-borne diseases. His group works on the pathogenesis of malaria during pregnancy and molecular methods for surveillance of malaria and drug-resistant malaria. They are using next-generation sequencing methods to understand malaria diversity, immunity and evolution. In addition, the group has been studying the prevention of tick-borne disease with permethrin-treated clothing and how the tick’s microbiome affect its ability to transmit disease.

Infectious diseases (ID) remain key public health problems. In the developing world, diarrheal infections, respiratory infections, AIDS, malaria and tuberculosis are the principal causes of morbidity and mortality. Globally, pneumonia, meningitis, and nosocomial infections remain serious and costly health problems. Global travel and migration increase everyone’s susceptibility to epidemic and emerging diseases, from both natural (e.g., bird flu) and deliberate (terrorism) causes. The emergence and dissemination of drug resistant microorganisms represent an expanding threat. At the same time, our abilities to develop and deliver new drugs and vaccines to control these diseases have also increased. Infectious disease epidemiologists are needed to improve surveillance, identify newly emerging infections, understand transmission dynamics, and develop and evaluate prevention and control strategies.
The ID epidemiology program at UNC benefits from a close collaborative relationship with other units at UNC, such as:
- Understand the pathogenesis of infectious diseases including:
- Route of pathogen entry
- Host responses, including innate and acquired immunity
- Relationship between disease and virulence factors, immune avoidance mechanisms, and pathogen host interactions
- Host and microbial genetic factors
- Be familiar with the natural history of major infectious diseases;
- Understand the social, economic, behavioral, demographic and environmental determinants of infections, particularly emerging infections;
- Understand the causes for the enormous disproportion in infectious disease burden between resource poor and resource rich countries;
- Understand the special status in infectious disease prevention and control in marginalized populations such as prisoners, homeless, uneducated and persons of color;
- Be familiar with key surveillance systems and other sources of data relevant to the problem;
- Understand strategies for early detection and control of episodes of bioterrorism;
- Understand the principles and practices of outbreak investigation;
- Be familiar with the broad principles of infectious disease prevention including strategic use of prophylactic vaccines and vector control;
- Be familiar with the basic strategies for treatment of infectious diseases including use of antimicrobials;
- Understand the principles associated with infectious disease elimination;
- Be familiar with the broad principles of infectious disease modeling;
- Apply epidemiologic methods in the design, conduct and analysis of infectious disease epidemiologic studies;
