I work as a Cell Culture Technologist in the MRC Centre for Medical Mycology and provide specialist support within the group for cell culture experimentation in host-pathogen research to tackle serious fungal diseases. I am also responsible for the day to day running, servicing and operation of the CMM tissue culture and sporulating fungal laboratories as well as training of tissue culture and sporulating fungus users.

Previously I was working in plant pathology, investigating the virulence of the wheat pathogen fungal species of Zymoseptoria tritici.

Before my interest focused on pathogenic fungi, I had been involved in several projects studying the virulence of human bacterial pathogens including gut pathogens (Clostridium difficile, Vibrio parahaemolyticus and Campylobacter jejuni) and bacteria causing respiratory diseases (Burkholderia pseaudomallei and Coxiella burnetii). The highlight of these research projects was identification of the CD0873 lipoprotein as an adhesin of Clostridium difficile, with Steve Michell and Rick Titball in 2014. Since role of CD0873 in adhesion was described, CD0873 has been widely studied by a number of research groups and been identified as a potential vaccine component against Clostridium difficile.

I have experience in a range of laboratory methods, such as

  • microbiological laboratory procedures with bacterial and fungal species at BSL2, BSL3, including handling of anaerobe bacterial pathogens
  • molecular biology methods, for example nucleic acid and protein techniques including transcriptomic and proteomics, genetic engineering and a range of phenotypic assays
  • infection procedures with cell cultures and wax moth larvae (Galleria mellonella)
