 Research Expertise & Professional Interests
Dr. Werler became Chair of Epidemiology in July 2014, following more than 28 years at the Slone Epidemiology Center at Boston University. She is a perinatal epidemiologist. Her research is supported by grants from NIH and CDC and include projects on maternal serum markers of infection and abdominal wall defects; gene-environment interactions and clubfoot; medications, folic acid intake, and inheritance in relation to spina bifida; biomarkers of hemostasis, vasculogenesis, and vitamin A pathways in relation to craniofacial anomalies; and psycho-social and cognitive outcomes in children born with craniofacial birth defects. She has published over 150 papers and book chapters; received the National Birth Defect Prevention Network Oakley Award, the Society for Pediatric and Perinatal Epidemiologic Research Mentoring Award, and the Teratology Society Fraser Award; and served on numerous NIH advisory and review boards. Dr. Werler is Director of the BU Reproductive, Perinatal, and Pediatric Epidemiology training program for pre-doctoral candidates in Epidemiology and teaches Design and Conduct of Case-Control Studies.
