Dr. Caudill is internationally recognized for her work on folate and choline, and the intake levels required to meet metabolic requirements and improve physiological outcomes. She has published over 120 papers, reviews, and chapters in this area, and is frequently an invited speaker on topics related to the importance of choline nutrition during pregnancy and lactation.  Dr. Caudill is also a co-editor on the popular graduate level nutrition textbook "Biochemical, Physiological, & Molecular Aspects of Human Nutrition”.

Research Program


A primary goal of the Caudill laboratory is to generate data that will inform the development of nutrient intake recommendations that promote mother and child nutrition, health and well-being.  An integrative approach which includes targeted and non-targeted assessments of genomic, epigenetic, biochemical and physiologic endpoints is employed.

Current Research Activities

Impact of maternal choline intake during pregnancy on DHA delivery to the developing fetus  (Dr. Melissa McDougall, Dr. Kevin Klatt, Dr. Siraphat Taesuwan, Dr. Devapatla and Dr. Vidavalur).

Influence of the gut microbiome on choline bioavailability (Dr. Melissa McDougall, Dr. Liz Johnson, Dr.Kevin Klatt, and Dr. Siraphat Taesuwan).


Professor Caudill has 140+ publications including 117 peer reviewed original research papers. Her CV provides a full list of her published work, and can be found at

I have taught the popular upper division Nutrition and Disease Course (NS 4410) for the past 10 years. As of Spring 2019, I will transition to Human Nutrition and Nutrient Metabolism (NS 3310). A top priority for me in my teaching and advising is to convey respect for the students and a sense that I care about their learning.

NS 4410  - Nutrition and Disease  (4 credit units). 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  of high current interest in the area of nutrition and health, case-studies and thinking critically activities (2008-2017)

NS 3310 Human Nutrition and Nutrient Metabolism (4 credit units) Organized in a lecture format with opportunities for class discussion, this course facilitates the students’ integration of biochemistry and physiology in the context of human nutrient metabolism, and strives to ensure that students will have a working knowledge of the sources, metabolism and function of each essential nutrient.
