Main subject of my research is focused on statistical properties of turbulence, with particular attention to active scalars and transport of buoyant and inertial particles. Applications of these studies can be found in geophysical flows, such as ocean and atmosphere, as well as in biophysical processes. One crucial problem in the oceanography concerns the interplay between turbulence and phytoplankton ecology (small-scale clustering, thin phytoplankton layer, sedimentation, nutrient uptake). I'm also interested in theoretical issues in turbulence theory, for example regarding the dimensional transition from 2D to 3D systems.
