Sea Level And Ice

Biography

The main focus is on sea ice retrieval algorithms development and analysis of sea ice behavior from multisource satellite observations. I am primarily studying sea ice with synthetic aperture radar and am trying to fill the gap between the world of science and real user needs such as ship routing in the ice, ice regime and end-to-end solutions for sea ice monitoring and management systems.
