Professor Per-Olof Berggren is Professor and Head of Cell Biology and Experimental Endocrinology, Department of Molecular Medicine and Surgery, Director The Rolf Luft Research Center for Diabetes and Endocrinology at Karolinska Institutet in Stockholm, Sweden. In 2013, Prof Berggren joined NTU as a Visiting Professor at LKCMedicine, Metabolic Disease Research Program. Prof Berggren acquired his PhD in Medical Cell Biology at the University of Uppsala and has published 383 articles in peer-reviewed journals.

Throughout his scientific career, Prof Berggren has done pioneering work regarding the fundamental mechanisms regulating the stimulus-response coupling in the endocrine pancreas with several seminal contributions within the fields of insulin secreting pancreatic beta-cell Ca2+ handling, phosphorylated inositol compounds and insulin receptor operated signalling.

Research Focus

The Berggren laboratory is interested in understanding molecular aspects of pancreatic islet cell biology, cell physiology, cell pathology, mechanisms involved in insulin secretion and glucose homeostasis,  Ca2+ signaling and cellular cross-talk.
