I am an experimental physicist with research interests including the physics of the heliosphere, ionospheres, magnetospheres, and near-Earth space, and dusty plasma phenomena. I use space and remote observations as well as model calculations for my research. Starting from experimental atomic spectroscopy my research interests developed toward space and astrophysics and in particular the physics of the heliosphere, cosmic dust and dusty plasmas; I also carried out research related to the evolution of small bodies, meteors, and meteoroids in the solar system and in extra-solar planetary systems. Motivated by new discoveries I got interested in cosmic nanodust and its dusty plasma phenomena. Through studies of the light scattering at irregular particles and through the meteor phenomena I became interested in atmospheric physics and the complex interactions of the polar atmosphere at all altitudes. I am currently engaged in radar observations and optical observations, rocket measurements, model calculation projects and data analysis projects.

At present, I am responsible for three externally funded projects:

Mesospheric Dust Project

Dust in the Heliosphere Project

EISCAT_3D Project (Research Infrastructure)

Statistical modeling and analysis of time series and spatial data.

Bayesian computation using the methodology of integrated nested Laplace approximation (INLA).
