Fragment Based Screening for new Antibiotics by Protein X-Ray Crystallography. Due in part to rising levels of antibiotic resistance, the death toll from pathogenic bacteria is expected to skyrocket over the next 15 years. There is therefore a pressing need for new antibiotics to treat bacterial infection.

Characterisation of a powerful molecular motor, the FtsK DNA translocase. The FtsK protein is a fast and powerful molecular motor, a pump that can, and does, move an entire bacterial chromosome. This project will uncover the detail of the mechanism used by this motor to convert the cell's chemical energy source Adenosine Triphosphate (ATP) into movement of DNA; revealing the molecular detail of a fast and powerful motor.
Visualising chaperones disentangle and refold proteins - one molecule at a time. Chaperones are enzymes that maintain the proper function of proteins in the cell. This research aims to visualise, at the single molecule level, how chaperones facilitate the folding of individual proteins and how they can disentangle proteins that have aggregated as a result of cell stress.
