Background and activities
Leif Rune Hellevik (1967) is a Professor at the Divison of Biomechanics, Department of Structural Engineering.
Since 2011, a primary focus of Hellevik's research has been the development of STARFiSh, which is an acronym for Stochastic Arterial Flow Simulations. In this research code models for pressure and flow waves of blood flow in arterial network are embedded in a framework which allows for uncertainty quantification and sensitivity analysis of all model parameters with respect to the model predictions.
NTNU Physiome, headed by Hellevik, is one of the R&D streams organized under NTNU Biotechnology- the Confluence of Life Sciences, Mathematical Sciences and Engineering, which is one of the three enabling technology programmes at the Norwegian University of Science and Technology.
He is also heading the NTNU intitiative IKTiSU, to promote the use of numerical methods and ICT in general in the enginering education at NTNU from 2013-2015.
