Research Description

My research focuses on the biogeochemical cycling on organic compounds in the ocean. So far, I have been working with phosphonates which are organic phosphorus compounds found ubiquitously in the ocean and associated with marine dissolved organic matter. After looking at their degradation by bacteria I am now trying to unreveal their biological sources and their functions which remains unknown in marine environment.
