Frederik Persson is a chief physician and senior researcher at the Steno Diabetes Center Copenhagen in the research group led by Professor Peter Rossing, which has a long-standing interest in the area of diabetic complications.

For the past 17 years, diabetic nephropathy and diabetic complications have been his main areas of interest. His research has spanned epidemiology, biomarkers and small explorative studies to participation in, and post-hoc analyses of, large randomised controlled trials. In particular, he has contributed to clinical research in relation to a new treatment concept, renin inhibition, exploring the potential for further renoprotection in patients with type 2 diabetes. This was also the topic of his doctoral thesis, accepted and defended in 2013 at the University of Copenhagen.

In addition to his clinical research, he spends 50% of his time in the outpatient clinic at Steno Diabetes Center Copenhagen, with a focus on development of the care and prevention of complications in people with diabetes. He has lectured on post-graduate courses and symposia in India, China, the Middle East and South America.
