A large part of the energy produced in the world is used to overcome friction between surfaces in contact. Friction is present everywhere where surfaces are moving relative each other. This means that there are large possibilities for energy savings by for instance increased component lifetime and enhanced performance as a result of smarter material choices and system design. One way to reduce the friction losses is to lubricate the surfaces in contact and relative motion. My research is focused on different types of lubricants. The applications have varied but some examples are a lubricating additive in fuel to reduce the fuel consumption in engines as well as greases with and without graphene for electrical contacts. I have also evaluated graphene in polymer composites. In my projects I have collaborated with Triboron International, Axel Christiernsson, ABB and Graphmatech.

By tribological testing in simplified lab tests that mimics the thought application we can widen our knowledge about friction- and lubrication mechanisms. Except from testing, analysis of surfaces after being in contact is an important tool to understand what and which changes on the surfaces, often in utmost surface layers, that influence the friction and lubrication.

I have a Master’s degree at Uppsala University in Science and Engineering with specialization in Chemical Engineering with a focus on materials.
