I have a range of academic and commercial work experience and have enjoyed working in different countries giving me an international perspective. My main research interests are in applied environmental microbiology with a current focus on the following topics:
1. Methods to reduce spoilage and microbial contamination of fresh ready to eat plant produce. Current projects are examining the ecology of Listeria in horticultural soils and the use of electrolysed water to reduce microbial loads on fruit and vegetables.
2. Soil microbial communities : I work on the effects of pollutants on soil microbes and how soil microbes contribute to plant growth e.g. the involvement of soil microbial populations in a phenomenon called yield decline that occurs in a variety of important crop types.
