Academic Lead for Admissions

My current research covers a range of areas including the identification of pathogens in clinical and other complex materials and this has been a major focus of my work for over 10 years. In addition, I have also developed research into the identification of novel approaches/drugs for the treatment of infection and the biochemistry/protein chemistry associated with pathogenicity of a range of protozoan and bacterial pathogens. To support my work, I have developed an international network of collaborators and have strong links with academics in the UK, NHS and industry.


Teaching and supervision

I currently teach all aspects of medical microbiology, introductory biochemistry and molecular biology on Medicine MBChB. I have successfully supervised 21 PhD and 4 MPhil/ MSc by research students on topics around various aspects of medical microbiology.

Research interests for potential research students

Research areas for potential PhD students focus on understanding the basic cell biology of a number of orphan parasites including Giardia and Acanthamoeba with respect to the identification of novel drug targets. In addition, I am interested in developing non antibiotic approaches to the control of pathogens and linked to this is the development of rapid detection for difficult to culture microbial pathogens. I am also interested in how we monitor microbial contamination of clinical environments.

Research

My research is diverse but has an overarching theme of infection control particularlywith respect to orphan infectious diseases. The information below gives a brief introduction to the work that I am currently involved in.

Giardia

Over the past 20 years I have been involved in studying the physiological adaptation of protist parasites to their environment in the host. This has mostly focused on the protozoan Giardia intestinalis, a human pathogen. During this time I have identified new metabolic pathways in this organism and have also characterised the biochemical process through which this organism survives in the gastrointestinal tract, in particular adaptation to an environment with variable oxygen concentrations - active oxygen species and oxidative stress. I have also been involved in a number of related studies looking at the process of cellular transformation in Giardia and the genetic plasticity of this species. All this work has been externally funded through Wellcome, The Leverhulme Trust and the National Institute of Health (USA).

Acanthamoeba

My research on Acanthamoeba has focused on the development of reagents that can be used for the rapid identification of this organism in both clinical materials as well as in the eye. This work has so far utilised bacteriophage display technology, however we will be starting work on the potential applications of chromogenic substrates. Alongside this we are utilising PDT to identify novel approaches for control of Acanthamoeba (currently no useful drugs available for treatment). We are also revisiting work initiated 10 years ago on mechanisms of pathogenicity in this organism.

 
Biofilms and surface chemistry

I am interested in the development of polymicrobial biofilms on medical devices and metarials and this follows on from previous work on the development of  a novel ‘biofilm resistant’ speech valve. This work was highlighted in the Times Higher Education Supplement and in The Engineer.

Technologies

Photodynamic Therapy
The development of novel approaches to control infection is a major research interest and we are currently looking at the potential of photoactivated drugs (PDT) to control problem microbial infections including wounds and localised parasitic infections.

Bacteriophage Antibodies
A significant proportion of my work with phage antibodies focuses on the application of phage technology as both a research and diagnostic tool. We are currently using this technology to develop useful peptides for detection and drug targeting.
