Research Degree Supervisor

I am a veterinary microbiologist with interests in human and veterinary public health. I have supervised and continue to supervise students working on antibiotic resistance, food borne diseases and Rhodococcus equi infections in foals.

Current Projects:

Development of a vaccine to control Rhodococcus equi in foals
 This project is to develop an adenoviral vector vaccine against Rhodococcus equi
Use of bacteriophage to control ETEC infections in pigs
 Bacteriophage have been collected from piggery effluent and other environmental sites with the aim of developing a panel that can be used to prevent and treat post-weaning diarrhoea in pigs
Use of bacteriophage to control Rhodococcus equi infections in foals
 The aim of this project is to isolate and characterise bacteriophage from Rhodococcus equi and determine if phage can play a role in controlling R equi infections
