Dr. Julie Goodman, Director of Gradient's Epidemiology Services, is an expert in epidemiology and toxicology. Her primary responsibilities include the design, oversight, analysis, and interpretation of epidemiology studies, the evaluation of chemical toxicology data, the analysis of apparent disease clusters, and the evaluation of specific environmental chemical exposures to assess potential human health risks.

Before joining Gradient, Dr. Goodman was a Cancer Prevention Fellow at the National Cancer Institute, where she conducted a number of molecular epidemiology studies analyzing relationships between inflammatory gene polymorphisms and colon cancer risk. She was also instrumental in the development of Polymorphism Interaction Analysis, a powerful statistical tool for cancer risk assessment. While a pre-doctoral student at Johns Hopkins University, Dr. Goodman conducted epidemiological and toxicological research in estrogen metabolism and breast cancer risk. Dr. Goodman has authored several peer-reviewed toxicology and epidemiology articles.
