Leif Rune Hellevik

About

Leif Rune Hellevik (1967) is a Professor at the Divison of Biomechanics, Department of Structural Engineering and since 2017 the Vice Dean for the master programs at the Faculty of Engineering at NTNU.

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.

A more recent project is "My medical digital twin (MyMDT). A digital twin for essential hypertension management and treatment." By a novel combination of exercise-, hypertension-, mathematical modelling-, machine learning-, statistical-, biosensor-, genetic epidemiology- and population based reseach, a personalized Medical Digital Twin (MyMDT) will be developed, that serve as a transformative platform for patient specific hypertensive intervention. MyMDT shall identify, and implement, primary and secondary hypertension prevention schemes to improve individual health outcomes and reduce health care cost. MyMDT will radically improve prevention and treatment of hypertension, and bring NTNU to the international forefront of translational hypertension research.

In the period 2013-2015, Hellevik headed the NTNU intitiative IKTiSU, to promote the use of numerical methods and ICT in general in the enginering education at NTNU.
