Bacterial DNA Repair and Mutagenesis


Uphoff Lab | Department of Biochemistry | University of Oxford

Our group investigates DNA repair and mutagenesis in bacteria. We seek to understand the mechanisms of DNA repair pathways and how mutation rates are regulated through DNA damage responses. Our goal is to directly measure these fundamental processes inside individual living cells. To this end, we develop single-molecule/super-resolution microscopy, single-cell manipulation, microfluidics, flow cytometry, and whole genome sequencing techniques. We also advance data analysis and computational modeling for quantitative descriptions of DNA repair and mutagenesis. We are currently very interested in the consequences of gene expression noise on the fidelity of genome maintenance. This work also informs about the origins of mutations that lead to antibiotic resistance.

Under the Lens

September 2018

We started a journal club with a bunch of groups at Oxford, where we take recent papers on Microbial Imaging "Under the Lens". This goes together with a new regular feature in Nature Reviews Microbiology. The first one is on "Filming flagella and pili in action". More details can be found here.
