Research

I am a senior research scientist in the lab group of Dr. Sharon R. Long. Our group studies the symbiotic, nitrogen-fixing bacterium, Sinorhizobium meliloti and its leguminous host plants (members of the genera, Medicago, Trigonella, Melilotus.) My research projects include characterization of symbiotic genes, regulatory circuits, S. meliloti genomics and global expression analysis.
