Current Professional Activities
Choline Coalition Advisory member 2008-present
The choline coalition is an organization whose mission is to encourage and promote the translation of quality choline research to practice in an effort to improve public health.

Invited international expert on “Micronutrient bioavailability: priorities and challenges for setting dietary reference values" organized jointly by the International Life Sciences Institute (ILSI) Europe Addition of Nutrients Task Force and EURECCA Network of Excellence. June 2009

Current Research Activities
At present, the Caudill lab is using a systems approach to investigate the differential effects of two doses of choline intake on metabolic, genomic and physiological endpoints in pregnant and lactating women, subpopulations that may have a high demand for this nutrient. Data generated from this study will provide metabolic and genomic signatures that can be used in determining nutrient intake levels that optimize maternal and infant health outcomes. The generated data can also scientifically guide the need for therapeutic intervention with choline in this sub-population.

Current Extension Activities
Economic Impact on the Local Community:
This year my reseach program has had a direct economic impact on the local community of at least $130,000 ($80,000 for study participant payments and ~$50,000 for local grocery purchases).

Recruiting Efforts:
We have also engaged in extensive recruiting activities and worked with the following agencies/businesses to inform the local community of the opportunities for participation in our research program: Tompkins County Health Department; Cayuga Medical Center; Ithaca Free Clinic - clinic for uninsured members of the community; WIC Program - provides food and care for pregnant women, infants and children; Medicaid Obstetrical and Maternal Services (MOMS) Program - medical care during and after pregnacy; Douglas of Ithaca - women pregnacy support group; Ithaca Birth Group - support group on topics related to pregnancy; Cornell Cooperative Extension; Tops; Greenstar; OB-GYN Associates of Ithaca; Ithaca VA Outpatient Clinic; Cornell Prenatal Yoga Class; Westview Apartments; Alphabet Soup; Buttermilk Falls Pediatrics; Ithaca Bakery; Women's Community Bldg

Biography

Biographical Statement
Marie Caudill received her PhD degree in Nutritional Sciences from the University of Florida in 1997. Shortly thereafter she became an Assistant Professor in the Department of Human Nutrition and Food Science at Cal Poly Pomona University in Southern California where she served for 10 years. Marie joined the faculty at Cornell University as an associate professor of Nutritional Sciences and Genomics in August 2007.

The Caudill laboratory investigates the effects of varied nutrient intakes (e.g. folate and choline) and genetic variation on metabolic, genomic and physiological endpoints in human study participants.  A systems approach incorporating both targeted and non-targeted analyses on a range of metabolites with known links to disease development and on readouts of global gene expression and stability is used. Stable isotopes (i.e., d9-choline) are also used to aid in the interpretation of the biomarker data. Results of these studies will scientifically inform the development of dietary recommendations designed to optimize human health and guide decisions on need for therapeutic nutritional interventions.

Teaching interests include nutrient metabolism, nutrition and disease, and nutritional genomics.

Courses Taught
NS6310 - Micronutrients: Function, Homeostasis and Assessment
Professor Caudill participates in this team taught course managed by Charles McCormick.   Specifically, she delivers lectures on the B-vitamins (folate, vitamin B-12, vitamin B-6, biotin) and choline.

NS 4410  - Nutrition and Disease
This course combines the principles of nutrition, biochemistry, physiology, genetics, pharmacology, and pathology to understand disease risk, prevention, progression and management. The course is organized in a lecture format with opportunities for the class to engage in the discussion of original research articles on topics of high current interest in the area of nutrition and health.
