Irena Krga, Ph.D.

  • Assistant Project Scientist
Dr. Krga’s research focuses on the role of dietary habits in pancreatic carcinogenesis and the development of strategies, including dietary interventions and novel pharmacological agents, for pancreatic cancer treatment. She also investigates the impact of diets, foods, and bioactive compounds in preventing or ameliorating cardiometabolic and age-related disorders. Using omics technologies (genomics, transcriptomics, and proteomics) combined with bioinformatics analyses, her research aims to identify key molecular targets and cellular pathways underlying preventive and therapeutic strategies across cancer, cardiometabolic diseases, and aging-related disorders.

Benjamin P. Hurrell, Ph.D.

  • Assistant Professor of Nutrition and Immunology
Dr. Hurrell’s lab explores the dynamic interplay between nutrition, metabolism, and immune regulation, focusing on how specific nutrients and metabolic pathways influence the development and function of immune cells in both health and disease, particularly asthma and allergy. Utilizing a variety of cutting-edge mouse models, including genetically engineered strains, specialized diets, and established asthma models, his team investigates the impact of dietary factors on immune responses and asthma pathogenesis. By applying techniques such as flow cytometry, transcriptomics, and metabolomics to profile immune cell populations and their metabolic states, the lab aims to identify innovative dietary strategies that can modulate immune function and improve lung health.

Amy R. Nichols, PhD, MS, RDN

  • Assistant Professor | Assistant Nutritionist in AES
  • Faculty member associated with the Master of Advanced Study in Maternal and Child Nutrition Program
Building on her extensive experience in maternal and child nutrition and dietetics, Dr. Nichols conducts interdisciplinary women’s health research in two primary areas at the intersection of dietetics, reproductive epidemiology, and cardiometabolic health. First, she investigates the nutritional, biological, and social aspects of the preconception period through the first 1000 days with a translational emphasis on modifiable determinants that affect the lifecourse. Second, leveraging longitudinal data, Dr. Nichols examines sex as a biological variable and the extent to which reproductive risk factors (e.g., infertility, pregnancy loss, reproductive senescence) are associated with body composition, cardiometabolic health, and the origins of disease among female individuals in midlife.

Laurie Nommsen-Rivers, PhD, RD, IBCLC

  • Academic Administrator
  • Adjunct Associate Professor
  • Faculty member associated with the Master of Advanced Study in Maternal and Child Nutrition Program
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.

Jennifer T. Smilowitz, Ph.D.

  • Assistant Professor of Cooperative Extension
  • Faculty member associated with the Master of Advanced Study in Maternal and Child Nutrition Program
Dr. Smilowitz has a well-established research career investigating the role of diet on the gut microbiome across the lifespan, with a particular focus on clinical nutrition and lactation during the first 1,000 days—from pregnancy through early childhood. As a Cooperative Extension Specialist with a background in lactation education, she leads collaborative, community-engaged outreach programs that support infant feeding and deliver evidence-based education on lactation and breastfeeding. Through integrated research and extension efforts, her work addresses critical gaps in health, strengthens community capacity, and advances strategies to reduce chronic disease risk.

Ryan G Snodgrass, Ph.D

  • Research Molecular Biologist, USDA ARS WHNRC
  • Adjunct Assistant Professor
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.

Guodong Zhang, Ph.D.

  • Associate Professor | Associate Nutritionist in AES
Dr. Zhang's research seeks to elucidate the molecular mechanisms for the health effects of dietary and/or environmental compounds, in order to better understand their metabolic individualities, address inter-individual susceptibilities, and clarify their health effects.

Eleonora Cremonini, Ph.D.

  • Associate Researcher
Dr. Cremonini's research focus on the effect of polyphenols consumption, especially epicatechin and anthocyanins, on metabolic-associated disorders. She uses cell and animals models and also clinical trials to investiagate the beneficial effects of these bioactives at the cellular level of the gastrointestinal tract (i.e., permeability, inflammation, and microbiota), which secondarily can mitigate obesity-associated pathologies, such as diabetes, steatosis and non-alcoholic fatty liver disease (NAFLD).

Andrew G. Hall, Ph.D

  • Assistant Adjunct Professor
  • Faculty member associated with the Master of Advanced Study in Maternal and Child Nutrition Program
Dr. Hall's research focuses on the assessment of zinc nutritional status and its relationship to health through the life course. Dr. Hall’s interests include the development of novel biomarkers of zinc-dependent functions, and the application of zinc tracer methodologies towards the determination of dietary zinc absorption and cellular utilization.
