Reprogramming of Escherichia coli K-12 metabolism during the initial phase of transition from an anaerobic to a micro-aerobic environment

The major theme of the research in my laboratory is bacterial gene regulation. We are interested in signal perception mechanisms (in particular oxygen); signal transduction (ligand induced protein confromational changes); interaction of transcription factors with the core transcription machinery; interactions between transcription factors to integrate multiple signals; and the influence of promoter architectures on these events. We are also interested in aome aspects of post-transcriptional ...

Work in my laboratory is focussed on microbial physiology - the study of how bacteria and other microorganisms work. Although rooted in the tradition of bacterial growth and intermediary metabolism, microbial physiology now embraces molecular biology, genetics, biochemistry, and indeed any discipline that can shed light on bacterial function. Much of our experimental work is conducted with Escherichia coli, the pre-eminent ‘model’ organism with unrivalled ease of genetic and physiological ...

I am a post-doctoral research associate working in Sheffield in the SUMO consortium. My research focuses on transcriptional regulation in E. coli, with particular emaphasis on the transcriptomic analysis of steady-state chemostat cultures using both microarray and qRT-PCR approaches.

Previous experience, especially that gained during my PhD, involved work on Salmonella physiology and lag phase growth, focusing particularly on gene-expression and transcriptional regulation. Other techniques used ...
