Professional Researchers, Lecturers and Adjunct Faculty

Laurie Nommsen-Rivers, PhD, RD, IBCLC

  • Academic Administrator
  • Adjunct Associate Professor
Dr. Nommsen-Rivers (she/her) is the incoming 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.

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.

Bess Caswell , Ph.D

  • Assistant Adjunct Professor, USDA ARS WHNRC
Dr. Caswell's research interests are in dietary assessment and analysis methods and food-based nutrition interventions. Her work incorporates nutritional epidemiology, community-based nutrition research and controlled dietary studies conducted at the Western Human Nutrition Research Center.

Eleonora Cremonini, Ph.D.

  • Assistant 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).

Dragan Milenkovic, Ph.D.

  • Associate Researcher
Dr. Milenkovic’s research aims to demonstrate impact of nutrients on development and prevention of cardiovascular and neurodegenerative diseases and to identify molecular and cellular mechanisms of actions underlying observed effects using multi-genomic and bioinformatic approaches. In the last 10 years his research has been particularly focused on protective effects of bioactive plant compounds, mainly polyphenols.

Roberta R. Holt, Ph.D.

  • Associate Researcher
Dr. Holt’s current research interests have focused on defining the metabolic and physiologic effects of the intake of specific foods on the cardiovascular health. This includes examining the relationship between circulating metabolites and vascular and platelet responses.

Ming-Fo Hsu, Ph.D.

  • Assistant Project Scientist
Dr. Hsu's research involves studying the molecular basis of protein tyrosine phosphatases (PTPs) in metabolic regulation. In particular, he uses state-of-the-art genetic (animal models of human disease), biochemical and pharmacological approaches to investigate the role of PTPs in diabetes and its complications.

Rulan Jiang, Ph.D.

  • Associate Project Scientist
Dr. Jiang’s research focuses on pediatric nutrition, specifically on absorption and biological roles of bioactive components in human milk, such as lactoferrin and osteopontin. She uses both cell models and animal models to investigate mechanisms by which milk derived bioactive compounds are absorbed and exert their multiple functions. In addition, she is interested in dynamic changes of milk bioactive components throughout lactation in human populations, as well as relationships between the changes and the health outcomes.

Katie Adams, Ph.D.

  • Associate Project Scientist
As an applied microeconomist, Dr. Adams’ research interests are primarily in development economics with a specific focus on maternal and early childhood undernutrition. At the interface of economics and nutrition, her research aims to improve our understanding of human behavior as it relates to health and nutrition and to translate that understanding into informed guidance on policies that improve nutritional and other outcomes in developing countries.
