Dr. Sandie Ha, Biostatistics UC MercedDr. Sandie Ha

Sandie Ha, Ph.D., is an Assistant Professor of Public Health at the University of California, Merced. Her research focuses on studying how various environmental exposures (e.g., air pollution, extreme temperature, pesticides) affect pregnancy and perinatal health outcomes including but not limited to gestational complications, stillbirth, preterm birth, and birth defects. She’s also interested in investigating how exposures during windows of developmental plasticity (e.g. pregnancy and early life) influences the risk of neurodevelopment in early childhood. Her other research interests include cardiovascular complications, asthma, cancer, and health disparity.

Sandie recieved her Ph.D. in Epidemiology and M.P.H. at the University of Florida, Gainesville. She received her B.S. in Biology/Physiology at the University of Washington, Seattle.
