My research activities are in the following fields:
• Theoretical fusion plasma physics (main research field)
• Computational physics
• Analytic philosophy
These are described in more detail below.
As a teacher, I have
- designed new undergraduate courses in engineering science, vector analysis
and fusion physics.
- developed course designs based on continual examination
as well as course development strategies for KTH.
• In 2014 I received the KTH Pedagogical prize.
• In 2022 I was elected "Teacher of the Year"
by the student programme Civilingenjör och Lärare.
Interpretation and prediction of fusion plasmas are complex tasks and cannot, as of yet, be made in detail from first principles. New methods for more efficient and accurate solution of the modelling equations are of importance for designing more advanced and compact fusion power plants that could replace fossil fuels by the mid-century or before.
• As a theorist I develop noveltheoretical and numerical toolsfor solving the systems of nonlinear partial differential equations that constitute our models of the hot fusion plasma. These fluid (3D space) and kinetic (6D phase space) equations feature phenomena on several distinct time scales, being demanding in terms of computer memory and CPU time. For this reason, my group focuses on efficient so-called time-spectral methods.
• My second field of interest is to exploreoperational limits of alternative plasma configurations. Such configurations, being more compact and easier to develop, would significantly shorten the time for commercialization of fusion power. Some major work (for details, see portfolio):
GWRM - a time-spectral method for solving initial-value PDE:s
A time-spectral approach to numerical weather prediction
Optimizing Time-Spectral Solution of Initial-Value Problems
SIR - an efficient root solver for systems of nonlinear equations
•Operational limits of fusion energy configurations
Effect of Thermal Conduction on Pressure-driven Modes in the Reversed-field Pinch
Numerical Studies of Confinement Scalings for the Dynamo Free Reversed-field Pinch
Confinement Scaling Laws for the Conventional Reversed-field Pinch
Linear Stability of the High Temperature, Dense Z-pinch
Large Larmor Radius Stability of the Z-pinch
•Fundamental plasma physics
Large Debye Distance Effects in a Homogeneous Plasma
On the Minimum Elementary Charge of an Extended Electromagnetic Theory
My work in analytical philosophy primarily addresses problems in epistemology and philosophy of mind. I have found that elements of physics and mathematics, including information theory, are beneficial when addressing long-standing problems relating to, for example, knowledge and understanding, consciousness and free will.
Publications (for details, see portfolio):
•Tankens Villkor, a book about the limits to rational thinking in mathematics, the natural sciences, philosophy and in everyday life;
•Understanding (published in the journal Filosofisk Tidskrift)

Teaching and pedagogy
• I have taught and held courses at KTH since 1977 in calculus, differential equations, algebra, vector analysis, fusion plasma physics, engineering science as well as in theory and methodology of science.
• Until retirement I have taught in the courses listed below. I have also been quite engaged in pedagogical leadership at KTH, recently as director of the Electrical Engineering (E2DOC) doctoral programme.

Novel structure for textbooks and nonfiction
Nonfiction and academic textbooks are still written in a similar style as in the 17th century, whereas the readers’ demands have evolved. But there is a way out! - see portfolio.
At KTH, as well as at other technical universities, work is still to be done for achieving gender equality. Some humble initiatives can be found in the portfolio.
