Main fields of research are as follows.

  • Characterisation of rare and new minerals, in particular titanosilicates and other minerals from hyperalkaline rocks. Synthesis of mineral phases; pillaring of heterophyllosilicates. 
  • Crystal-chemistry and crystal-physics of inorganic compounds. 
  • Structural and general crystallography. 
  • Modular crystallography; polysomatism, polytypism and twinning. 
  • Results have been obtained mainly by diffraction (X-rays, neutrons, electrons) and electron microscopy. 
  • The main results can be grouped as follows. 
  • Characterisation of some 80 mineral species; most of them with crystal structure determinations; 33 are new species [altisite, balangeroite, bykovaite, canavesite, carbokentbrooksite-(Ce), carlosturanite, caryochroite, cattiite, eveslogite, ferriallanite-(Ce), gjerdingenite-Fe, hydroxylclinohumite, kalifersite, kanonerovite, kapitsaite-(Y), kristiansenite, labuntsovite-Fe, labuntsovite-Mg, magnesiocloritoid, magnesiodumortierite, manganonaujakasite, nabalamprophyllite, nafertisite, nechelyustovite, neskevaaraite-Fe, phaunoxite, potassicarfvedsonite, raadeite, seidite-(Ce), shirokshinite, stoppaniite, tsepinite-Ca, zirsilite-(Ce)]. Some new species are connected with asbestos (balangeroite, carlosturanite), very high pressure metamorphism (magnesiochloritoid, magnesiodumortierite) and hyperalkaline rocks (e.g., Kola Peninsula). 
  • Evolution with temperature and pressure of the crystal structure and equation of state of rock-forming layer minerals, in particular micas. 
  • Development and applications of the theory of polysomatism [inophites (carlosturanite), heterophyllosilicates (nafertisite) and palysepioles (kalifersite) series have been defined]. 
  • Theoretical studies of twinning (merohedry; definition of allotwins, plesiotwins, metric merohedry, selective merohedry, hybrid twins, and polyholohedry) and diffraction methods. 
  • Contributions to bond valence and charge distribution theory; crystal-chemistry of the hydrogen bond.
