Research Publications
The O’Brien Laboratory is working to understand the nutritional, endocrine, and genomic factors that interact to regulate calcium, vitamin D, and iron homeostasis. Our publications cover a wide range of topics, including the use of stable mineral isotopes as tracers in our studies. Learn more about our research and findings below.
