Research project: The Type VI Secretion System in commensal Neisseria spp.


I am currently investigating a type six secretion system in commensal Neisseria spp.

  • Research degree: MSc by Research
  • Title of project: The Type VI Secretion System in commensal Neisseria spp.
  • Research supervisor: Dr Lori Snyder


I worked from 1996 - 2010 in industry labs, these included molecular biology research, forensics, genotyping and trace residue analysis. I came to Kingston to study after finally working in the NHS for a short while. After graduating from Kingston, I was offered a job as a Graduate Teaching Assistant. I am now a full time member of staff and studying for my Masters in reearch part time.
