ABOUT THIS SITE

This is my personal site for various rock mechanics related work. I am currently working as a consultant for Vattenfall Power Consultant AB, but my background is in research/academia, as well as the mining industry. This site includes selected publications, presentations and rock mechanics projects. If you have any suggestions, or if you are missing anything, please contact me. Below you will find my CV in short form. Selected projects are also presented here.
