Research Interests

Biofilm and microbial ecology. Focus areas: anaerobic biofilm reactor technology for biorefining, energy production and wastewater  the microbial ecology of anaerobic biofilms and soil ecosystems; biofilm infection control. I also have a strong interest in translational aspects of research and a low-temperature anaerobic process, developed in NUIG, is currently being commercialised as part of a spin-out company. I am the lead scientist in the Irish Bioenergy and Biorefining Technology Centre, which works on behalf of Irish enterprises to develop the indigenous environmental technology sector.
