Since I received my PhD from the University of Oslo in February 2006, I have been working as a Post Doc at the Cardiac Computation project.

I have for long been concerned with mathematical models which describe cell signaling in excitable media. My project involves numerical

analysis in terms of finding a priori bounds on solutions of differential equations for electrical pulse propagation throughout the cardiac

tissue. In particular, I study simulations of cardiac arrhyhtmia, and defibrillation as a treatment of such. Due to the electric shock

given through electrodes, large voltage gradients are present, and sophisticated numerical algorithms are required in order to obtain an

adequate numerical solution. Currently I am investigating the effects of three, instead of the normal two, shock electrodes on the atria. This

involves both theoretical investigation as well as extension of code for our cardiac simulator . The goal is to find an electrode configuration

which leave the application of the electric low-volt shock painless.
