Introduction
My current line of research is molecular ecology of the rhizosphere. I work on phosphate/arsenate transport and biodiversity of arbuscular mycorrhizae. Applied research involves developing agrobiologicals with application in maize, beans and chickpea. Currently, we work on the basic aspects of a tripartite bacterial-fungal-plant interaction of a Bacillus cereus strain which has been identified as a biocontrol agent of the Fusarium verticillioides fungus causing fusariosis of maize.
