Gene expression is the vital path that converts DNA information into functional proteins. Our group studies mechanisms and machines of gene expression using single-molecule biophysical methods and biochemistry. We observe single biomachines in real time, both "in vitro" and inside living cells. We also develop single-molecule fluorescence methods, instruments, assays and DNA-based biosensors.

Our team is a Biological Physics research group within Condensed Matter Physics. We are also linked to many of the Oxford Doctoral Training Centres (DTCs) and the Wellcome Trust graduate programme in structural biology.
