Dr. William Grant, PhD

William B. Grant, PhD, was educated as a physicist at University of California, Berkeley, and had a 30-year career in laser remote sensing of atmospheric constituents. His foray into health studies resulted in the first article linking diet to risk of Alzheimer’s disease in 1997. His next major article, in 2002, greatly expanded the list of types of cancer that UVB exposure reduced through vitamin D production.

After retirement from NASA in 2004, he founded Sunlight, Nutrition and Health Research Center (www.sunarc.org), a non-profit organization in San Francisco, dedicated to research and education regarding preventing and treating chronic and infectious diseases through diet, vitamin D, and sun exposure. His publications include articles and/or reviews on Alzheimer’s disease, autism, cancer, dental caries, influenza, periodontal disease, pneumonia, pregnancy, rheumatoid arthritis, vitamin D fortification and supplementation, and methodological aspects of epidemiological research. He turned his attention to the role of vitamin D in reducing risk of COVID-19 in early 2020 and has published several reviews on the mechanisms and epidemiology. A review he organized on vitamin D and COVID-19 has over 850 citations at Scholar.google.com. He has 284 publications on vitamin D listed at pubmed.gov. He ranks in the top ten of Expertise in Vitamin D: Worldwide.
