Mary Alice Smith

Environmental Health Science
Professor Emeritus

Environmental Health Science

Dr. Smith’s research focused on the effects of microbial and chemical agents on pregnancy and development. Her research incorporates use of animal models and in vitro models for pregnancy and development, determination of dose response for adverse effects, and the use of embryonic stem cells and metabolomics to predict adverse effects. These data were used to develop risk assessments for microbial pathogens to determine the level of exposure that would likely result in adverse pregnancy outcomes or adverse health effects to children.
