Her research aims to improve female reproductive health with a focus on reducing the burden of menstrual dysfunction, subfertility and infertility. Difficulty conceiving a pregnancy is a pressing public health problem that affects millions of U.S. women. Factors that affect fertility are not well-understood. At the same time, menstrual cycles are a vital sign for reproductive-aged women, yet menstrual cycle research is lacking. Her hypothesis-driven and translational research investigates environmental exposures that can influence menstrual cycles, fertility, or early pregnancy including vitamin D, air pollution, and ambient heat. Dr. Jukic received a B.S. from the University of Notre Dame and joined the Peace Corps after graduating. She obtained an Emergency Medical Technician license before earning an M.S.P.H. from Emory University, and a Ph.D. in epidemiology from the University of North Carolina at Chapel Hill. She completed a postdoctoral fellowship at NIEHS and was an Assistant Professor at the Yale School of Public Health before joining NIEHS as a Principal Investigator. Her research group develops and rigorously applies epidemiologic methods, including leveraging mobile app health data to explore and describe reproductive health endpoints.
