Maura E. Walker, PhD

Assistant Professor, Boston University College of Health & Rehabilitation Sciences: Sargent College

Biography

Dr. Walker is an Assistant Professor in the Department of Health Sciences at Boston University’s Sargent College of Health and Rehabilitation Sciences and in the Section of Preventive Medicine and Epidemiology at the Chobanian & Avedisian School of Medicine. She serves as the Principal Investigator of the Quantitative Nutrition and Metabolism Lab and co-leads the cross-university Digital Health and Network Multi-Omics Lab.

As a transdisciplinary nutrition scientist, Dr. Walker has conducted extensive research across preclinical, clinical, and epidemiologic domains, examining the influence of diet on various biological systems, including transcriptomics, proteomics, metabolomics, and gut microbiota. In her role as a Junior Investigator with the Framingham Heart Study, her primary research focuses on using both traditional and systems-level epidemiological methods to deepen our understanding of how modifiable risk factors can alter the life-course progression of cardiometabolic diseases, with a particular emphasis on MASLD, diabetes, and cardiovascular diseases.

Dr. Walker earned her MS and PhD in Biochemical and Molecular Nutrition from the Tufts Friedman School of Nutrition Science and Policy, where she also conducted research at the USDA Jean Mayer Human Nutrition Research Center on Aging. She teaches SAR 783 Metabolomic Regulation and SAR 785 Research in Clinical Nutrition for BU’s Masters of Science in Nutrition degree programs.
