Overview

Infectious diseases are responsible for millions of deaths each year, especially in the developing world.  Our program has expertise in a variety of infectious diseases including those that are sexually transmitted diseases, air-borne and vector-borne.   There are two NIH training grants that support students.  We have close collaborations with the Division of Infectious Diseases in the School of Medicine, the Department of Geography, the Carolina Population Center, FHI, the North Carolina Department of Health, and many triangle-based research organizations.

Faculty-Research

(* indicates primary advisors for ID epidemiology PhD students)
Dr. Allison Aiello is a professor of epidemiology and leads the social epidemiology program. Aiello’s research investigates socioeconomic and race/ethnic disparities in infectious diseases, the relationship between infection and chronic diseases, and prevention of respiratory infections in the community setting.

Dr. Ralph Baric, professor of epidemiology and microbiology and immunology, is an internationally recognized expert on noroviruses and SARS coronavirus. His group has been interested in aspects of host and viral genetics and how they relate to understanding pathogenesis and developing control tools. Baric’s research also focuses on identifying the molecular mechanisms governing emerging virus cross species transmission and pathogenesis in humans and identifying the viral and host determinants which influence susceptibility to infectious diseases.
