Scientific Activity

Research interests focus on quorum sensing signaling in synthetic and natural multispecies communities associated with plants. The role of cell-cell signaling in emerging bacterial plant pathogens and beneficial endophytes, especially of the rice plant, are currently studied. Novel interkingdom signaling circuits between plants and plant associated bacteria are also of interest.

Published 120 papers in international peer-reviewed scientific journals.
