Endocrine disrupting chemicals, maternal-child health, reproduction and development, vulnerable populations


Dr. Julia Varshavsky is an Assistant Professor of Environmental Health at Northeastern University, with a joint appointment in the Department of Health Sciences, Bouvé College of Health Sciences, and the Department of Civil and Environmental Engineering, College of Engineering.

Julia previously worked at the Office of Environmental Health Hazard Assessment (OEHHA) in the California Environmental Protection Agency as a research scientist in epidemiology and biostatistics to conduct biomonitoring studies of health-related chemical exposures.

Her most recent position prior to joining OEHHA was as a postdoctoral researcher in environmental epidemiology and biostatistics for the Program on Reproductive Health and the Environment (PRHE) at the University of California San Francisco (UCSF), where she conducted biologically-based population-level studies on exposure and health risks associated with endocrine-disrupting chemicals (EDCs), including polybrominated diphenyl ethers (PBDEs), per- and poly-fluorinated alkyl substances (PFASs), and organophosphate flame retardants (OPFRs). Specifically, her recent work highlights maternal-fetal exposure to PBDEs, PFASs, and OPFRs during mid-gestation in relation to biomarkers of placental development and disease that are associated with maternal and fetal health complications.

Julia aims to improve public health by studying reproductive and developmental health impacts related to EDCs commonly found in consumer and personal care products and identifying opportunities to reduce exposure and associated health risks among vulnerable populations. Julia earned her MPH and PhD in environmental health sciences at the University of California, Berkeley School of Public Health. Her dissertation research focused on developing methods for; characterizing disparities in; and evaluating dietary sources of cumulative phthalates exposure. Prior to graduate school, Julia facilitated scientific dialogue and research translation around developmental impacts of environmental contaminants as the reproductive health working group coordinator for the Collaborative on Health and the Environment (CHE). Julia studied molecular biology as an undergraduate and contributed to laboratory research that improved chemical screening methods in water through microarray development.
