Senior lecturer in Computer Science and 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.


Since 2020 I am a part of the Computer Science department, teaching courses in Internet of Things, Web Intelligence and Python programming.

My previous academic carreer, I have been teaching the pumping technology course, hydromechanics and machinery systems for the marine engineer programme.


In my research I have studied energy efficiency in shipping from the data perspective. 

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.
