Janneane Ferguson Gent PhD

Research Scientist in Epidemiology (Environmental Health)

Research Interests

Air pollution; Childhood asthma

Research Summary

Dr. Gent’s primary research focus is the effects of air pollution on childhood asthma. She is a co–investigator on studies specifically focused on exposure to traffic, a major source of air pollution in our region. These studies take advantage of the large data base of ambient air contaminants measured by the Environmental Protection Agency (EPA) at central monitoring sites. Using this information as well as data collected by the research team at the CPPEE inside and outside of study subjects’ homes, Dr. Gent and her colleagues hope to contribute to the understanding of public health effects of short–term exposure to traffic–related air pollution.

Dr. Gent has served as a consultant for the EPA reviewing literature on the effects of nitrogen dioxide and particles on health. Her work for the EPA contributes to the production of their Integrated Science Assessments for these pollutants. This in turn is an important step in the regulatory process that leads to the setting of the National Air Quality Standards.

Dr. Gent is also a co–investigator with Melinda Pettigrew, Ph.D., School of Public Health, Division of Epidemiology of Microbial Diseases, on a study of microbial interactions of pathogens involved in otitis media.
