Prof. Ilya Usoskin is the head of Oulu Cosmic Ray Station and vice-Director of ReSoLVE Centre of Excellence, an expert in cosmic-ray and heliospheric physics, solar physics and geophysics. He was graduated in 1988 as M.Sc. in Space Physics from Leningrad Polytechnics, obtained a degree of Cand.Sci. in Astrophysics from A.F. Ioffe Physical-Technical Institute (St. Petersburg, Russia) in 1995, and a PhD in Space Science from the University of Oulu in 2000. He worked as a postdoc at INFN (Milano) in 1997-1999, and as the head of Oulu Cosmic Ray Station since 2000.

Prof. Usoskin serves the scientific community as an expert, being, in particular, a member of C4 (Astroparticle Physics) commission of IUPAP (International Union of Pure and Applied Physics), member of commission E3 of IAU (International Astronomical Union), member of Research Council of Russian Academy of Sciences, etc. He has several awards, including the Knight's cross of the 1st class of the Order of Lion of Finland (2013) and Julius Bartels medal of European Geoscience Union (2018), an award of the University of Oulu for outstanding contribution to research (2018), ISEE award (Japan, 2020).
