In the last 9 years since becoming an independent researcher, as part of the Advanced Therapeutics Group here in the School of Dentistry, I have had over £2 million in research funding.  This has included industrial funding from a long-standing collaboration (over 9 years) with Algipharma AS, and a more recent collaboration with the Life Sciences company, Qbiotics Ltd; both projects involving undertaking translational research into novel antimicrobial compounds.  Further research funding has also come from the Norwegian Research Council funding the industrial partnership with Algipharma AS and collaboration with the Paper Research Institute (PFI), Trondheim. 

My current anti-biofilm research involves translation of research to clinical practice using 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 has recently completed Phase 2b clinical studies in cystic fibrosis patients.  Work is ongoing to elucidate the mode of action of OligoG.  The Advanced Therapeutics Group recently won the prestigious Cardiff University Innovation and Impact Award in Medicine (2017) for our research in this area. 

Further funding from the Norwegian Research council has financed a project involving the development of biocompatible cellulose nanomaterials (derived from wood pulp) for advanced wound healing applications in conjunction with the Paper Research Institute (PFI), Trondheim.  The ability of these nanofibres (from renewable sources) to interact with complementary polymers and form novel material structures for use in applications as diverse as wound dressings and graft scaffolds for tissue engineering in a range of human diseases has formed the basis of our on-going research.  Furthermore, testing of these prototype dressing materials

More recently, in collaboration with the life sciences company Qbiotics Ltd, Queensland, Australia I have begun a new study looking at a series of natural and semi-synthetic compounds derived from the Queensland rainforest, which have considerably efficacy in wound healing, to characterise their antibacterial/antibiofilm properties.

Research Interests

I have had a keen research interest in Wound Healing for many years.  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.  In this, I attempted to investigate both the disease association of specific bacterial groups and the relationship between microbial bio-burden and healing in these chronic wounds.  This included the use of culture-independent approaches to clinical microbiology and the involvement of uncultivable prokaryotes in wounds.  The specific role of antimicrobial resistance and bacterial virulence of MRSA in particular, in these hard-to-treat wounds has also been investigated.  More recently, my work has focused on biofilms in wounds, including the use of in vitro tissue models to assess the invasive properties of Candida albicans and antimicrobial testing of in vitro wound biofilms and wound dressing materials.
