Environmental flows and climate dynamics. Experimental investigation of stratified and rotating flows, chaotic advection dynamics, statistical analysis of climatological data banks,
Recent European collaborations:
Environmental optics. Environmental optics, atmospherical optics, polarization patterns, imaging polarimetry, polarized light pollution, polarization insect traps.
Global energy problems; environmental radiations: Investigation of environmental problems of energy systems, external costs of renewable energies with special emphasize on energy application of water, wind and biomass. ― With the help of a larger group of students research is conducted in order to get experimental data for the exposimetry in the GHz range (e.g. mobile phones).
Natural radioactivity: radon mapping, geological source of radon, radon as a tracer gas, radon in built environment. Renewable energy: feasibility and new methods for energy production.
