Currently, my main research topic is nitrogen metabolism in the green microalga Chlamydomonas reinhardtii and how mutualism with other organisms such as Methylobacterium improves that assimilation. I have also worked for many years on molybdenum cofactor biosynthesis, characterizing the function of the enzymes CNX1G, CNX1E and MCP. In recent years, we have also characterized the function of the molybdoenzyme NOFNiR (crARC) and its involvement in the synthesis of nitric oxide and nitrous oxide.
