Thomas Jonsson

Thomas Jonsson is an Associate Professor at KTH Royal Institute of Technology in the Division of Electromagnetic Engineering and Fusion Science within the School of Electrical Engineering and Computer Science. His research focuses on fusion plasma physics with particular emphasis on modeling plasma heating, stability, and confinement. He is actively involved in studies of plasma heating by radio waves at the JET experiment in Oxford and serves as task coordinator for heating and current drive modeling within the EUROfusion Consortium.

Jonsson's research interests span plasma physics, fusion energy, electromagnetic engineering, radio frequency heating, and computational plasma modeling. His work centers on the development and application of advanced computational methods for understanding wave-particle interactions in fusion plasmas, particularly ion cyclotron resonance heating (ICRH) techniques. He investigates plasma stability mechanisms, confinement properties, and heating optimization strategies for tokamak devices, with direct applications to ITER and future fusion reactors. His research bridges theoretical modeling with experimental validation at major international facilities.

Analysis of Jonsson's recent publications reveals a strong focus on computational methods for radio frequency wave propagation in tokamak plasmas, disruption prediction techniques, and experimental validation of heating schemes. His work demonstrates increasing sophistication in modeling approaches, with growing integration of machine learning techniques for plasma control. The research spans fundamental plasma physics to applied engineering solutions for fusion reactors, with particular attention to ITER-relevant scenarios and DEMO design considerations.

As an educator, Jonsson teaches a range of courses including Plasma Physics (EF2200), Electromagnetic Waves in Dispersive Media (ED2210), and Project in Fusion Research (ED2247), serving as examiner and course responsible for several advanced courses. His teaching spans both Master's level courses in electromagnetic theory and plasma physics, as well as specialized PhD courses on charged particle motion, plasma waves, and fusion research.

Jonsson maintains active collaborations with major European fusion research institutions, particularly through the EUROfusion Consortium, and contributes to the JET experimental program. His work supports the international effort toward practical fusion energy by addressing critical challenges in plasma heating and stability for next-generation fusion devices.
