Currently (2020) I am on a teaching sabbatical at the University of British Columbia in Vancouver, BC, Canada.


Senior lecturer in Marine Engineering.

I started my career in the Royal Swedish Navy in 2001, and have sailed as a Marine Engineering officer on fast attack crafts, corvettes and submarines. During these years I have worked with gas turbines, diesel engines as well as battery electric propulsion. I live in Kalmar and have a wife and two kids. I have a keen interest in new technology and is also an amateur runner. In my spare time, I am always busy with hobby projects and reading books. I have also been active as a chairman of the Kalmar Secular Humanists, promoting a secular and scientific worldview.


I have been teaching the pumping technology course for the marine engineers since 2010. The course comprises basic knowledge in hydromechanics as well as choosing the right pump in a certain system.

I am also involved in developing IoT-courses for the electricial programme.


In my research I have studied energy efficiency in shipping.

The studies are about Organic Rankine cycles (ORC) and energy and exergy analysis, as well as machine learning (ML) methods for energy predictions. The research is an applied research with a marine engineerings approach. This means that I am focused on research based on operational data and results that can be applied on board.
