Dr. Laugero's lab studies stress and nutrition interrelationships. Research is being conducted to understand physiological and metabolic underpinnings of inter-individual variability in stress responsiveness, and how this can be used to explain vulnerability or resilience to the negative mental and physical effects of chronic stress. A systems approach is applied to examine the interrelationships between stress, diet, and physical activity in animal models, humans, and the community to identify mechanisms and factors that explain differential regulation of the stress response.

Dr. Lemay's lab studies how dietary components, especially fermentable carbohydrates, affect host response and whether that response is modulated by the functional capabilities of resident microbiota.

Dr. Newman's research group is developing and applying targeted and untargeted metabolomics tools to investigate metabolic responses to diet and their implications in the context of obesity and its associated co-morbidities. Active research areas include: 1) Investigating the functional implications of lipoprotein particle metabolomics structure on vascular and adipose physiology; 2) Investigating cross-talk between mediators of energy metabolism, inflammation, tissue growth and satiety; 3) Mapping the natural variance in metabolic responses to dietary challenges; 4) Investigating the impact of diet quality and weight maintenance/loss on metabolic indices of health; 5) Developing analytical tools for the quantitative assessment of dietary intake.

Dr. Nommsen-Rivers (she/her) is the director of the Maternal and Child Nutrition Master of Advanced Study program and the UC Davis Human Lactation Center. Her program of research aims to strengthen the evidence base for supporting optimal clinical management of lactating parent-infant dyads. Her current work focuses on physiologic factors that influence milk production during lactation.

Dr. Snodgrass's research is focused on understanding how diet and nutritional and metabolic status shape innate immune function. Active research areas include: 1) investigating how metabolic status influences innate immune cell frequencies and phenotypes; 2) investigating the impact of diet and stress on cardiovascular risk factors and innate immune cell phenotypes; 3) investigating how microbiota-derived metabolites, which can be influenced by our diet, contribute to innate immune cell function.

Dr. Wessells' research interests are focused on micronutrient deficiencies among infants and young children in low-income countries, and the evaluation of therapeutic and preventive interventions designed to improve nutritional status in these populations. She is also interested in the dietary and biochemical assessment of nutritional status, and relationships between nutritional status, intestinal mucosal function and infection. She has extensive expertise in designing and implementing randomized controlled trials, as well as conducting systematic reviews and meta-analyses.
