Current fields of scientific interest:

- Evolution of comets and asteroids - numerical simulations and laboratory measurements in vacuum. Investigations include the evolution of the structure of a material on micro- and macro scale, as well as the relation between the topography of comets and their activity.

- Evolution of ice moons of giant planets.

Past fields of research:

- Evolution of surface- and subsurface ice on Mars including conditions of the appearance of liquid.

- Long scale evolution of the global ecosystem.
