Short Bio
Experience : Dr. Nicolaas Deutz, MD, PhD currently serves as Director for the Center for Translational Research in Aging and Longevity (CTRAL). For more than 30 years, his research background and expertise focus on nutrition, metabolism, and physiology studies involving the use of stable isotope methodologies, both in humans and animals. Dr. Deutz has extensive experience with isotopic calculations, validation and data interpretation. The stable isotope approaches are used in several studies to unravel the metabolic changes in patients with chronic diseases (i.e., chronic obstructive pulmonary disease, cancer, cystic fibrosis, chronic heart failure, obstructive sleep apnea, mild cognitive impairment and dementia, autism spectrum disorder). This research leads to new insights in protein and amino acid kinetics in subjects with chronic disease and resulted in specific recommendations to nutritional supplements as method for reducing muscle wasting. Recently, he started studying the anabolic effects of specialized nutritional supplements in different chronic diseases and models of disease. Using translational approaches is a logical extension of the body of his research in the field of protein and amino acids metabolism. Education: Dr. Deutz obtained his MD and PhD at the University of Amsterdam, Netherlands. He is a medical physiologist and Nutrition Physician Specialist.
