Dr. Rebecca Schmidt, PhD

Rebecca Schmidt

Co-Director, Integrated Health Sciences, Environmental Health Sciences Center

Dr. Schmidt is a molecular epidemiologist. She studies how exposure to nutrition and the environment interact with the genome to influence the development of children's brain or central nervous system from a mechanical and pathways perspective, especially when a baby is developing during pregnancy.
