Owen FentonResearch Officer - Water Quality
I am a research officer with Teagasc since 2005. My research covers topics from soil physics, land drainage, hydrology, hydrogeology and environmental engineering. I presently am adjunct lecturer in NuiGalway, editor on Journal of Agriculture Science and the Irish Journal of Agriculture and Food Science, external examiner for Agriculture at WIT, on the management committee of an EU COST Action Connecteur representing Ireland and I am a leading partner of the H2020 Marie Curie ITN INSPIRATION due to start in April 2016 relating to soil and groundwater remediation.
