Ilya G. Usoskin[2] is a Finnish astrophysicist who is a professor at University of Oulu and head of Cosmic Ray Station at Sodankylä Geophysical Observatory. He is a Vice President of the International Astronomical Union since 2021.[3][4]
Education
[edit]In 1982, Ilya Usoskin graduated from the Saint Petersburg Lyceum 239[5] with intensified study of physics and mathematics, in parallel with Grigory Perelman. Then he became a student at the Peter the Great St. Petersburg Polytechnic University and finished it as an MSc in physics (Space Physics) in 1988.
Career
[edit]Since 1988, he worked as a junior researcher in the field of Astrophysics at the Ioffe Institute, where he obtained the Candidate of Sciences degree in astrophysics in 1995.[6] During 1997–1999, he was a postdoctoral researcher at the INFN Milano working on the Alpha Magnetic Spectrometer experiment. [7] Since 2000, he has been a staff of the University of Oulu—head of the Oulu Cosmic Ray station. [8]
In 2000, he got PhD in Space Physics,[1] in 2002, he became a Docent, and a full Professor in 2012.[9]
Recognition and honors
[edit]- 2013: Knight's Cross, First Class, of the Order of the Lion of Finland for the promotion of national science.[10]
- 2015-2024: member of C4 (Astroparticle Physics) of IUPAP. [11]
- 2018: Julius Bartels medal of the European Geosciences Union for the foundation of the Space Climate discipline.[12]
- 2019: elected member of the Finnish Academy of Science and Letters.[13]
- 2020: Annual Award of the ISEE of Nagoya University[14] for research of extreme solar events.
- 2021-2027: Vice President of the International Astronomical Union.[3]
Research
[edit]Usoskin works in the fields of Solar Physics, Cosmic Rays, Heliosphere and Space Climate. He has co-authored more than 400 research publications with tens of thousands of citations.[15][16]
His main research achievements include:
- Foundation of a new research discipline Space Climate, focused on long-term global changes in the terrestrial and near-Earth environment;
- Invention of a novel method to model atmospheric effects of cosmic rays;
- Invention of a novel method of past solar activity reconstructions using cosmogenic isotopes;
- Foundation of a new paradigm of extreme solar events known also as Miyake events.
