Curriculum Vitae

Professor Johnson’s main areas of expertise include health disparities, survey methodology and health behaviors in disadvantaged populations. Within the field of survey methodology, his work has focused primarily on sources of measurement and nonresponse error. His measurement error work is concerned with cultural variability in the cognitive processing of survey questions, an area in which much of his work has been invested over the past decade. He has also conducted numerous investigations designed to validate self-reported health information. His work on nonresponse error has been directed at developing new methods for identifying the effects of nonresponse mechanisms on the quality of survey estimates, as well as the development and testing of new approaches to adjusting for nonresponse bias. Johnson has also invested considerable effort in examining the health behaviors of disadvantaged populations. Among the disadvantaged populations he has worked with are homeless persons, immigrants, cultural minorities, criminal justice populations and mental health populations. Some of the health behaviors he has examined among these populations include cancer screening, nutrition, physical activity, tobacco use, alcohol consumption and drug abuse.
