Overview

With a long standing interest in wound healing, my early research focused on wound microbiology and ecology, and defining the molecular and cellular mechanisms involved in impaired wound healing in chronic, non-healing wounds.  This research pioneered analysis of the wound microflora using culture-independent 16S rRNA molecular analysis.  

My current research involves translation to clinical practice of a novel oligosaccharide antimicrobial derived from seaweed, OligoG (in conjunction with the biopharmaceutical company Algipharma AS, Norway) which offers the opportunity for new approaches to the management of human chronic diseases such as cystic fibrosis and chronic obstructive pulmonary disease (COPD).  This first oligosaccharide nanomedicine to treat multi-drug resistant gram-negative & biofilm-related infection in man has been patented, seeing translation from the laboratory into patients in less than 10 years.  OligoG is safe for human use and is currently in Phase IIb/III clinical studies in cystic fibrosis patients.  Work is ongoing to elucidate the mode of action of OligoG.  

More recently, in collaboration with the life sciences company Qbiotics Ltd, Queensland, Australia, I have been characterising the antibacterial/antibiofilm properties of a series of natural and semi-synthetic compounds derived from the Queensland rainforest, which have already been shown to have considerable efficacy in wound healing as immunomodulators.
