Thomas Svava Nielsen, PhD, studied molecular biology at the University of Aarhus, Denmark (MSc 2008) and obtained his PhD (2012) in molecular endocrinology and metabolism at Aarhus University Hospital, Denmark, studying human obesity and type 2 diabetes. Since 2012, Thomas has been working at the Novo Nordisk Foundation Center for Basic Metabolic Research, University of Copenhagen, Denmark. Here, he has trained to become an experienced microsurgeon, and his research agenda focuses on the development and refinement of advanced in vivo techniques for stress-free rodent metabolic phenotyping. He is competent in multiple state-of-the-art techniques in freely moving, conscious mice, including hyperinsulinemic-euglycemic clamps, tissue-specific metabolic flux measurements, and continuous glucose telemetry. Thomas is a senior instructor at RRSSC on our Glucose Clamp Course.
