About Me

I am currently a PhD student studying at the School of Life Sciences at the University of Warwick with Dr Meera Unnikrishnan. My research revolves around the nosocomial pathogen Clostridioides difficile and its interactions with the human gut, specifically adherence and colonization. I also delved further into its capabilities in stress response and persistence.
That being said, I am interested in all things microbiology and keen to learn as much as possible. I love working in the lab, trying new things every other week, debugging and coming up with wacky ideas. Feel free to contact me via email or Twitter (see below).


Research Interests

Current Projects

  • Elucidation of Clostridioides difficile proteins involved with host-pathogen colonization at the University of Warwick with the Unnikrishnan Lab.
  • Uncovering the σB stress response mechanism in Clostridioides difficile at the University of Warwick with the Unnikrishnan Lab.

Previous Projects

  • COG UK Consortium. A nationwide project carrying out whole-genome sequencing of SARS-CoV-2 (COVID-19) isolates with the aim of monitoring transmission and identifying variants. My role in this project involved library preparation and sequencing of inactivated clinical samples at the University Hospital of Coventry and Warwickshire.
  • Determining the efficacy of bacteriophage cocktails for treatment of Clostridioides difficile using Galleria mellonella as an infection model, at the University of Leicester with Professor Martha Clokie.
  • Workshop Co-ordinator and Technician for the Second East African Phage Workshop at Pwani University, Kenya, with Phages for Global Health.
