The Artificial Pancreas Trondheim (APT) research group was established in 2013 at The Norwegian University of Science and Technology (NTNU) in Trondheim. APT is a cross-disciplinary group of researchers with high competence in the fields of control engineering, biomedical engineering, biosensors, applied clinical research, endocrinology, anesthesia and intensive care medicine, pharmacology, biotechnology, mathematical modelling, biochemistry and chemometrics, as well as collaboration with relevant biosensor industry. The long-term aim of APT’s research is to develop a robust closed-loop glucose control system for patients with diabetes mellitus type 1 and 2 and for intensive-care patients, and to commercialize an artificial pancreas based on these results.
