Research interests

Rapid point of care detection of Antimicrobial resistant (AMR) bacteria

By 2050 it is estimated that 10 million people world-wide will die as a result of being infected with drug- resistant bacteria (Lord Jim O’Neil, 2014). Bacteria which were previously susceptible to antibiotic treatment have evolved to develop resistance to commonly used antibiotics, rendering them ineffective to combat infection. Now there are fewer antibiotics available to treat patients with certain infections. Hence, there is a global drive not only to discover new antibiotics to combat these bacteria, but also to develop new types of diagnostics that can help diagnose infection at point of care.

My research focusses on designing rapid, point of care nucleic acid-based assays for detection of AMR resistance genes. This research is highly interdisciplinary in nature utilising microwave engineering (in collaboration with Cardiff University) to liberate bacterial/spore DNA and DNA electrochemistry within the assay itself. A key part of this research includes integration of the assay into novel label-free biosensors (in collaboration with Plymouth University) and understanding the mechanisms by which microwaves interact with the bacterial DNA. 

I have 10 years of experience in development of novel microwave enhanced rapid diagnostics for microbial detection.

INTERVIEW on my research (Royal Society of Biology): https://www.youtube.com/watch?v=jC9Qy_o8e3U

Areas of expertise associated with the above include: Field effect transistors, thin-film transistors, Microwave engineering, aptamer design, aptamer-functionalisation of nanoparticles, microwave-accelerated metal enhanced fluorescence, microbial bioinformatics and biosensor development.

C. difficile Infection control:

Clostridium difficile is the primary cause of hospital acquired infection globally. In the US it contributes to 14 000 deaths/year, costing ~$1 billion annually (CDC, USA), while in the UK between 2006-2011 it was responsible for 29 425 deaths, (Office for National Statistics) costing £500 million/year. Its spores are resistant to desiccation and microbicide treatment and are able to persist on surfaces for months. My research focusses on understanding how C. difficile spores adhere to varying clinical surfaces and respond to biocidal insult, as well as using next generation sequencing techniques to understand spore epidemiology.

 Antimicrobial Peptides

I have an ongoing interest in the discovery and activity of novel antimicrobial peptides from invertebrates.

Research degrees awarded to supervised students

I have independently supervised both undergraduate and postgraduate students.
