Krzysztof Mizerski has experience in theoretical fluid mechanics in particular the theory of stratified convection and the hydromagnetic dynamo theory. All of his works have been concerned with analytic approaches to hydrodynamic and MHD problems supplied by numerical models. In collaboration with Professor Chris Jones from the University of Leeds, they have developed an effective theory of fully developed stratified convection and constructed a consistent dynamical picture of the phenomenon. The second main topic of the research conducted by Krzysztof Mizerski is the description of large-scale hydromagnetic dynamo effect in the fully nonlinear regime via the renormalization group method.
