Dr Enright is a microbiologist with research experience in Environmental Microbiology, Molecular biology, Microbial Ecology and Bioremediation. After the completion of her B.Sc. (Hons) degree in Microbiology in 2002, she began her PhD studies, and investigated low-temperature anaerobic treatment of synthetic pharmaceutical wastewaters, with reference to both the microbial ecology and process technology. She completed her PhD programme in autumn 2006. From 2007 to May 2010, she worked as a postdoctoral research scientist in both the Microbial Ecology Lab (MEL) and the Microbial Ecophysiology Research Group (MERG). While working in Galway Dr Enright has also supervised several final year projects during her role as a postdoctoral scientist and acted as a mentor to several PhD students in NUIG which has led to the publication of several peer reviewed research papers. Dr Enright has taught at several third level colleges including National University of Ireland, Galway (NUIG) and the Galway-Mayo Institute of Technology (GMIT). She has been employed as an assistant lecturer in IT, Carlow since September 2013 and is currently involved in several postgraduate research project;
