Research Interests

My research interests includes isolating and characterising organic pollutant degrading bacteria, isolating heavy metal resistant bacteria, plant growth promoting  bacteria and their growth promoting traits,  bacterial genomics, uses of plant associated bacteria as biocontrol agents, bacterial biosensors, plant microbiomes, waste water bioremediation, human pathogens survival in the plant biosphere, and genetic characterisation of Brassica napus.

Engagement and Collaboration

Over the past 5 years I have been involved in 10 industry based research projects including projects involving  wood spalting fungi, seaweed based fertilisers, improved chemical flocculation in waste water treatment, oil and PAH soil remediation, synthetic chemical markers  for diesel,  and developing  functional food products. I am also involved in secondary school science promotion programs such as the Young Scientist competition and primary school programs such as Cell Explorers. I am a member of professional bodies such as Environmental Sciences Association of Ireland, Association of Applied Biologist and the Society for General Microbiology.
