I am a Wellcome Trust Early-Career Fellow working on bacterial DNA damage repair mechanisms at the Centre for Bacterial Cell Biology (Faculty of Medical Sciences / Biosciences Institute). My lab specialises in deciphering fundamental DNA damage repair mechanisms in Gram-positive bacteria including the model pathogen Staphylococcus aureus.

S. aureus is the leading Gram-positive bacterium causing death from bacterial infections worldwide and is becoming increasingly resistant to our last-resort antibiotics. Treatment with several classes of antibiotics leads to generation of reactive oxygen species causing DNA damage such as single- and double-strand DNA breaks, and these damages can lead to cell death if not repaired. However, bacteria can evade DNA damage and at present, we lack a full understanding of the critical repair pathways underpinning this process.

The Winterhalter lab aims to uncover the full repertoire of essential proteins involved in DNA repair in S. aureus and to determine the critical interactions leading to DNA damage repair. Driven by fundamental science, we also investigate the requirement of repair pathways for virulence and their potential to be targeted by small molecule inhibitors. In the future, these essential repair processes could serve as efficient targets for alternative antimicrobial drug development.
