Emma Moynihan, PhD, MPH is a Senior Scientist at Exponent with expertise in environmental epidemiology and exposure assessment, pharmacoepidemiology, and real-world evidence (RWE) methods. She holds a doctorate in Environmental Health Sciences from the Johns Hopkins Bloomberg School of Public Health. and was a Johns Hopkins Data Science Fellow.

Dr. Moynihan's pharmacoepidemiology practice spans post-market safety surveillance, pharmacovigilance, regulatory submissions, and real-world evidence study design for pharmaceutical and biotechnology clients. She applies epidemiological and biostatistical methods to drug safety questions across therapeutic areas including oncology, metabolic disorders, and rare disease, delivering work products for both regulatory and litigation contexts. Her experience includes FDA Adverse Event Monitoring System signal detection, systematic literature review, and critical appraisal of clinical and observational evidence. She has extensive experience assessing epidemiology study design, methodology, and causal inference across observational studies and is proficient in R, Python, STATA, SQL, and ArcGIS.

Her environmental epidemiology practice focuses on the critical evaluation of epidemiological literature involving, for example, per- and polyfluoroalkyl substances (PFAS), electromagnetic fields (EMF), pesticides, heavy metals, and ambient air pollutants. Her work also includes infectious disease epidemiology and foodborne outbreak investigations.

Prior to joining Exponent, Dr. Moynihan supported epidemiologic surveillance programs for federal agencies including the CDC and NIH at ICF, where she contributed to survey design, qualitative research, and quality control across large-scale public health studies including the CDC's Foodborne Disease Active Surveillance Network (FoodNet). Her dissertation applied epidemiologic methods to evaluate whether environmental risk factors including pesticide exposure and heat stress were associated with kidney disease in the NIH Agricultural Health Study, a large prospective cohort of more than 50,000 pesticide applicators. During her PhD, she also received a Certificate in Risk Sciences and Public Policy.
