The Rolf Nevanlinna Institute is a research institute of Department of Mathematics and Statistics that concentrates on mathematics and statistics and their applications in various areas of science. We currently have three research groups in inverse problems, biomathematics and biometry. The research includes both theory and applications, bringing pure and applied mathematics and a wide spectrum of interdisciplinary scientific and industrial topics together. RNI has a wide collaboration network, including research contacts in industry and the public sector.
