Dr. Aschengrau has conducted epidemiologic research on environmental pollution and the risk of disease for over 30 years. In particular, she has led investigations on the relationship between drinking water contaminants and abnormal pregnancy and birth outcomes, neurological and behavioral disorders, and cancer, and on the impact of lead hazard reduction measures among inner-city children. She is currently the principal investigator of a cohort study examining the impact of environmental and social stressors on substance use. In 2003, Dr. Aschengrau published the the first edition of the textbook, Essentials of Epidemiology in Public Health, with coauthor George R.
