Sorina Eftim

Senior Manager, Epidemiology
Sorina is an epidemiology expert with more than 15 years of experience in environmental risk and toxicology projects.

Sorina uses statistical analyses to evaluate the health effects of air pollution, environmental epidemiology, and cancer epidemiology. She has performed statistical analyses for time-series and cohort studies of air pollution. Sorina has also conducted systematic literature reviews and meta-analyses on the risk of asthma in children and traffic-related air pollution exposures, and she has critically reviewed epidemiological studies for publication.

Sorina was the lead epidemiologist and biostatistician of a systematic literature review to examine the evidence for or against differential health risks associated with various water-based recreational activities in ambient waters contaminated by fecal material. She also performed a meta-analysis on the association between fluoride exposure and the level of children's intelligence. Sorina has experience using large, nationally available databases such as the National Health and Nutrition Examination Survey and National Health Interview Survey, as well as Medicare to design and analyze the potential health effects of various environmental agents.

Sorina has managed our support of the Environmental Protection Agency’s (EPA) Office of Water activities to facilitate criteria development, implementation, and water reuse efforts since 2012. She developed quantitative microbial risk assessments to estimate human health risks from various exposure routes and water reuse scenarios. Currently, Sorina leads our support for the implementation of Action 2.3.1 under EPA’s National Water Reuse Action Plan, which seeks to advance the consideration of water reuse to improve the security, sustainability, and resilience of the country’s water resources.

Sorina is currently Adjunct Professor at the George Washington University. She serves as a peer reviewer for several scientific journals, including Water Research, Environmental Health Perspectives, Environmental Research, and Emerging Themes in Epidemiology.
