Precision Nutrition
Studies that focus on heterogeneity in diet-related effects. Large clinical- and population-based studies are often used as they provide inter-individual variation in exposures and outcomes. Data that captures individual-level heterogeneity in processing of nutrients and their differential health effects as captured with genetic, microbial, and metabolome data.
Diet studies using big data, either in terms of big numbers of research participants and/or large numbers of data points (e.g., molecular, genomic, environmental, nutrient)

Diet, Health and Disease
Studies that focus on the connection between dietary intake and health and disease. Studies may focus on direct associations between nutrition-related exposures and health outcomes or they may be focused on methodological strategies and innovations to measure diet-related exposures. A major departmental focus is on obesity and its role in other diseases. Given differential effects of diet exposures at different points in the lifecycle, a major focus is on addressing short- and long-term nutrition-related impacts.

Nutrition MechanismsBasic science studies that use cell, animal, or human models of nutrition-related impacts to understand mechanisms of health and disease. Studies may focus on basic physiological mechanisms, absorption, distribution, metabolism, and excretion pathways and cover topics ranging from immunology to chronic disease.

Understanding and Changing Diet Related Behavior
Studies that focus on the behavioral aspects of diet, nutrition and lifestyles. Studies that develop a better understanding of the placement of behaviors in social and biological context. A significant area of research is in behavioral change and interventions involving novel methodologies for intervention tools, design, and analysis. Broad policy-related science is also a major focus, including societal, community, and local settings as well as novel methodologies for policy evaluation. Many department faculty focus on weight management and obesity-related behaviors.
