研究领域

Microbial development, gene regulation, and transcriptional control of gene expression. My lab primarily focuses on two aspects of development in the Gram negative social soil bacterium Myococcus xanthus: 1) identifying the hierarchical regulatory network that initiates and drives the developmental program and 2) determining the developmental link between DNA replication and the developmental program. In both instances we rely on the transcriptional analysis to monitor progression through development. My lab is also interested in the evolution of bacterial development in these ubiquitous bacteria and identifying core genes in the developmental process.
