Research Interests

The central theme of my research is the study of the interactions between heterotrophic bacteria and colored (CDOM) and non-colored dissolved organic matter (DOM) and of the degree of linkage between autotrophic and heterotrophic micro-organisms. I also look at how anthropogenic impacts such as increased pCO2 and inorganic and organic wastes alter the transfer of carbon between these two compartments.
