Judith S. Douglass, R.D.

Ms. Douglass, a Registered Dietitian, has over 30 years experience in developing data resources and analysis strategies to address clients’ needs for information related to nutritional epidemiology, food composition, and food safety. She is highly experienced in conducting survey-based analyses of exposure to foods, ingredients, nutrients, and other food constituents in the U.S. and other countries, providing clients with key data for nutrition status reports, food safety assessments, product development, and product marketing. She has developed exposure analysis models using multivariate regression analysis to identify demographic and health factors associated with intakes of foods, ingredients, nutrients, and other food constituents by subpopulations in the U.S. and other countries. She has also modeled subpopulation intakes to determine the effects of changes in ingredients and nutrient fortification on nutrition and health status measures. Ms. Douglass has experience in preparation of GRAS dossiers and has worked extensively with expert panels convened to evaluate safety of proposed new food additive uses. Ms. Douglass has completed all coursework required to earn a Ph.D. in Epidemiology at the Johns Hopkins University Bloomberg School of Public Health, and is currently conducting dissertation research on relationships between environmental exposures and health.
