I was for five years professor of hydrogeology of solid rocks at the University of Bergen, Norway. There I taught courses on fluid transport in porous and fractured media. My research in hydrogeology has primarily been on ground water transport in fault zones, including the effects of earthquakes on ground water transport and yield of wells.  I have also worked on the effects of dykes and low-permeability fault cores in collecting and transporting ground water. Dykes are particularly important in many areas, such as in desert areas, where much of the ground water is collected by and transported along dykes.

My students and I use field observations and analytical and numerical models to study ground water potential and transport. For the numerical modelling, we use the finite-element method and the boundary-element method, as well as standard hydrogeology programs.
