Present research activities cover basic research in several fields of modern physics as condensed matter, biophysics, space physics, subnuclear physics), as well as selected fields of chemical sciences, biological sciences and nanotechnology.
- Department of Subnuclear physics- Department of Space physics- Department of Magnetism- Department of Low temperature physics- Department of Metal physics- Department of Biophysics- Department of Theoretical physics - Laboratory of Materials physics- Laboratory of Nanomat. and applied magnetism- Laboratory of Experimental chemical physics
Currently the Institute employs about 130 people, more than half being research scientists, and about 16 post-graduate students.

- Cosmic rays - Space weather - JEM-EUSO project - Based on the Japanese Experiment Module (JEM) on the International Space Station, JEM-EUSO is a new type of observatory that will utilize very large volumes of the earth's atmosphere as a detector of the most energetic particles in the Universe. JEM-EUSO (EUSO for "Extreme Universe Space Observatory") observes the very short flashes of light in the earth's atmosphere caused by particles arriving from deep space.
