Dr. Zabotin's research is focused on development of new and advanced methods of remote sensing of the environment using general principles of wave physics. His studies have resulted in development of the next generation of advanced fully-digital ionospheric sounders (Dynasondes) and in new methods for plasma irregularity diagnostics. He has done pioneering work in theoretical and experimental studies of the multiple scattering effects in irregular ionospheric plasma, in application of passive noise interferometry in oceanography, and in establishing statistical properties of angular variations of relic radiation in cosmology. Most recent studies have been devoted to connections between the infragravity wave activity in the ocean and acoustic gravity waves in the atmosphere.
