Experimental Systems Biology

Our group studies cellular core networks of prokaryotic organisms with a strong emphasis on experimental systems biology approaches. Our group develops new high-throughput strategies to functionally decode microbial genomes. Our major interests are:

  1. Understanding the basic operating system of a bacterial cell
  2. Investigating genetic programs that orchestrate complex traits such as microbe-plant symbiosis
  3. Elucidating the transcriptional regulatory networks that coordinate the extraction of genomic information in bacteria

Our work at the interface of systems and synthetic biology focuses on the bacterial cell-cycle model organism Caulobacter and the nitrogen-fixing plant symbiont Sinorhizobium.
