Research in the laboratory focuses on three interconnected topics:

RNA metabolism in long-term nutrient starved bacteria

Recent publications: Switzer et al 2020 McQuail et al 2020

Phage takeover of bacterial transcription and other processes

Recent publications: Mulvenna et al 2019 Tabib-Salazar et al 2019

NEW: Transcriptional regulatory basis of bacteriocin expression in mono and polymicrobial environments (in collaboration with Syngulon)

If you are interested in collaborating with us please get in touch. We are always looking for enthusiastic MRes, MSc or PhD who are keen to join the group or visiting students looking to spend some time in the UK working in the area of molecular bacteriology.
