Giorgia Rutigliani

PhD candidate in Nutrition Science with experience in human research, sensory science, and data analysis. Currently working on two ongoing human studies, including a controlled dietary intervention on grain foods and an observational study on GLP-1 receptor agonists and sensory function. Actively engaged in refining study methods, preparing ethics and regulatory documentation, and implementing research protocols, with primary responsibility for data cleaning and analysis. Experienced in scientific writing and peer review. Motivated to translate rigorous science into insights that inform health and behavior.
