Allison, PhD, Professor of Pediatrics, Endowed Chair, and Director of the USDA Children’s Nutrition Research Center at the Baylor College of Medicine. Together, they explore what rigor, reproducibility, and trust truly mean in modern science, particularly within nutrition and obesity research.
During their conversation Dr. Allison reflects on his interdisciplinary career and current research at the Baylor College of Medicine and the USDA, while highlighting translational work spanning maternal and child health, nutrition, and performance outcomes. The two also explore key threats to scientific rigor, including bias, incentives, and institutional pressures, alongside limitations in peer review and common statistical pitfalls, ultimately emphasizing that science should be guided by data, methods, and logic, with evidence informing, not dictating, public health decisions.S
