Here are my key on-going projects

  • Finnish Centre of Excellence in Research of Sustainable Space (FORESAIL): Academy of Finland funded centre of excellence led by Prof. Minna Palmroth (University of Helsinki). The centre aims at  sustainable utilisation of space by focusing on understanding the near-Earth radiation environment and solving the space debris problem with innovative new technologies.
  • ERC Consolidator Grant project (1.6.2017 – 1.6.2022): My ERC project is focused on the initiation and evolution of coronal mass ejections (CMEs). We model and analyse two key CME structures and their interactions, the CME flux rope and the turbulent sheath by combining novel data-driven simulations and comprehensive data analysis. The key is to determine at the first time systematically the magnetic structure of the erupting CME.
  • SMASH (1.8.2017 – 31.7.2021): Academy of Finland funded Shocks and MAgnetoSheaths in the Heliosphere (SMASH) Consortium (led by Prof. Tuija Pulkkinen, Aalto University) focuses on identify the physical processes governing the formation and properties of shocked plasma and their propagation and interactions in the heliosphere, including the solar wind and terrestrial planets (Mercury, Venus, Earth, Mars).
  • UH Three-Year Funds project (1.1.2015 – 31.12.2017): This project develops novel physics-based and data-driven coupled coronal simulation. The project have produced photospheric electric field inversion toolkit ELECTRICIT that we in particular use to drive a magneto frictional simulation in the inner corona. The project results can be seen at
  • Heliospheric Shock Database: UH space physics team has developed and maintains the comprehensive Database of Heliospheric Shock Waves. The database includes fast forward and fast reverse interplanetary shocks observed by a large number of spacecraft, straightforward data search and sort options, plots and ASCII download. I am the PI of this project

Past key projects

  • HELCATS 1.5.2013 – 30.4.2017: European Commission funded HEliospheric Cataloguing, Analysis and Techniques Service (HELCATS) (led by Rutherford Appleton Laboratory, UK) is a consortium of nine institutes and universities. Using heliospheric wide-angle imaging, HELCATS tracks the evolution of coronal mass ejections (CMEs) and co-rotating interaction regions to the orbit of the Earth and beyond. UH is a Task leader of Work Package 4, which focuses on the building of a comprehensive interplanetary CME catalogue.
  • SWIFT: Academy of Finland funded Solar Wind Fluctuations and Magnetosheath Transport (SWIFT) Consortium (led by Prof. Tuija Pulkkinen, Aalto University) focuses on processes in the near-Earth space. At UH we focus in particular on determining how fluctuations in the solar wind affect solar wind magnetospheric coupling efficiency and on the processes at the magnetospheric boundaries (e.g., Kelvin-Helmholtz vortices). I am co-PI of this project
