Joshua W. Miller, Ph.D. is Professor and Chair of the Department of Nutritional Sciences at Rutgers University. He earned his Ph.D. from the Friedman School of Nutrition Science and Policy at Tufts University in 1990.

Dr. Miller’s research focuses on the role of nutrition in brain health, cardiovascular health, and aging. His work examines B vitamins—including folate, vitamin B12, vitamin B6, and riboflavin—and their involvement in one-carbon metabolism and homocysteine regulation. He also studies vitamin D and its relationship to cognitive function, blood pressure, and chronic disease risk.

A central area of Dr. Miller’s research investigates the connections between nutritional status and neurodegenerative diseases such as Alzheimer’s Disease and related dementias. His work has contributed to understanding how vitamin deficiencies and metabolic biomarkers may influence cognitive decline in aging populations.

Dr. Miller uses a range of research models—including cell culture, animal models, and human population studies—to investigate nutrient metabolism and its implications for disease prevention. His research also focuses on improving the assessment of vitamin B12 status and absorptive capacity, helping to refine clinical biomarkers used in nutrition and aging research.

Dr. Miller has authored numerous peer-reviewed publications in leading journals and has contributed significantly to the understanding of nutritional influences on neurological health, cardiovascular disease, and aging.
