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.
Join our group for your PhD
Students interested in joining our lab for their PhD (starting in October 2019) can apply to different graduate programs at Oxford University. The first application deadline is Friday 11 January 2019. Find out more and contact Stephan directly.
Upcoming conferences and seminar talks
Wellcome-Beit meeting in London. 3rd December 2018
Seminar at Newcastle University. 13th February 2019
Choosing the right label for single-molecule tracking in live bacteria: Side-by-side comparison of photoactivatable fluorescent protein and Halo tag dyes is now published in the Journal of Applied Physics D. Well done Nehir and Jarno!
Biochemical Society Prize for Emma Jones
Emma Jones has been awarded a Biochemical Society Prize in recognition of her research project and contribution to the lab. Many congratulations!
New article published
Real-time dynamics of mutagenesis reveal the chronology of DNA repair and damage tolerance responses in single cells, in PNAS. See also the commentary by Bennett van Houten and Neil Kad.
Special Edition of Current Opinion in Microbiology co-edited with Ariane Briegel.
Under the Lens
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.
Wellcome to new students
Three new students are joining our group this autumn: Lois Ogunlana - Interdisciplinary Bioscience DTP programme - jointly supervised with Craig McLean in Zoology. Madeleine Hooper - Biochemistry Part II student. Mayisha Sultana - exchange student from Princeton.
Oxford Conference: Single Molecule Bacteriology
9-12 September 2018
We co-organized the 84th Biochemical Society Harden Conference on Single Molecule Bacteriology.
