Research interests/expertise

Infection prevention and control and includes:

Activity and mode of action of disinfectants and sterilants: involvement in the assessment of the activity and mode of action of a new high level disinfectants. I have been responsible for leading the microbiology aspects of randomised controlled trials (for example, the use of brushes and picks in surgical scrubbing and the efficacy of body washing). I have also conducted studies investigating the possible link between biocide use and antibiotic resistance.

Development of novel antimicrobials/ disinfectants: I have collaborated with Prof Huddersman (De Montfort University) to develop a novel antimicrobial catalyst which has been patented; and with other colleagues to test novel compounds and natural products for antibacterial activity.

Efficacy of travel hand rubs: I have worked with Prof L Goodyer to investigate the antiviral activity of commercially available travel hand rubs and develop more effective formulations.

Evaluation of test methods for antimicrobial fabrics: Collaborations with the textile research group (TEAM) in the Faculty of Art and Design, have focused on the antimicrobial efficacy of fabrics.

  • Molnlycke Heath Care £25K ‘whole body washing randomised controlled trial on healthy volunteers’, March-May 2010. Principal investigator Prof Judith Tanner, Dr S Walsh responsible for microbiology aspects of the proposal/trial design and line management of the microbiology research associate. This pilot study is intended to lead to a larger study looking at the effect of body washing on hospital inpatients.
  • Hospital Infection Society Small Research Grant £5K awarded to Prof J Tanner. Nail brushes and nail picks during the surgical scrub to reduce bacteria on hands: a randomised controlled trial. Microbiology aspects led and designed by Dr S Walsh, 2008-9.
  • Hospital Infection Society Small Research Grant for £5K entitled ‘Biocidal activity and resistance and effects on antibiotic susceptibility’, 2002-current.

Internally funded research project information

  • Internally allocated doctoral training grant (fees only studentship Mr K Omoniala) ‘modified titanium as an antibacterial biomaterial’. Awarded to Dr D Armitage, Dr S Walsh and Dr J Tanner (2011).
  • HEIF 4 pump priming £9,300 awarded to Dr S Walsh and Dr K Laird to purchase a MAS-100 Microbial air monitoring system and obtain a Hazard Analysis and Critical Control Point (HACCP) level 4 qualification.
  • Internally allocated doctoral training grant entitled ‘Development of a broad spectrum, sporicidal, cost saving disinfectant incorporating a novel antimicrobial catalyst’, 2009-12.
