I have wide-ranging research interests which may be broadly classified aiming to understand responses to stress in various hosts; plants or humans. Thus, my work focuses on the key areas of food security and clinical health. Further details of my research can be accessed via the links below.
In my Food Security Research, I am interested in developing our understanding of the genetic and biochemical events associated with plant responses to stress and in identifying sources of tolerance/ resistance. This work is based on the use of model plant species, Arabidopsis and Brachypodium distachyon and also crops, wheat (Triticum aestivum), oats (Avena sativa) tomato (Solanum esculentum) and barley (Hordeum vulgare).
My interests in clinical health are focusing on the respiratory tract and on identifying drug leads from natural products. Lung cancer (LC) is the most prevalent cancer in the world with 1.3 million deaths recorded each year. Only 15% of patients live for five or more years after initial diagnosis; primarily; due to its late detection. Chronic obstructive pulmonary disease (COPD) is characterised by an increase in mucus production due to hyperplasia of goblet cells and hypertrophy of mucus glands COPD is a leading cause of death, arising from acute exacerbations - sudden worsening of symptoms - which may be triggered by infection or environmental pollutants. My research in this area is focusing on the detection of metabolite biomarkers for LC and COPD and investigating possible links with the lung microbiome.
My research in bioactive natural products focus on identifying anti-microbial metabolites – against such human pathogens as MSRA and Pseudomonas aeruginosa - from invasive plant species and extremophile microbial strains.
I employ cutting edge genomic and post-genomic approaches but will use classical physiological, genetic, biochemical or microbiological approaches- as appropriate. I have numerous national and international collaborations which are supported by funding from the BBSRC, the EU, NSF (USA), DEFRA, The Royal Society, the Welsh Assembly, and he A.U. Research Fund.
