Biography:
In addition to being a PI and researcher at the Ryan Institute, she recently served as Vice Dean for Teaching and Learning in the College of Science and Streamleader for Environment and Biotechnology within the School of Natural Sciences at NUI Galway. She completed an MA in Academic Practice in 2009, was awarded the NUI Galway President’s Teaching Award in 2009 and a national award by the National Academy for the Integration of Research, Teaching and Learning (NAIRTL) in 2010. |
Research Interests
| Algal biology, ecology and biotechnology. Research interests focuses on ecological and metabolic responses of algae (seaweeds and microalgae) to their environment (including effects of climate change and anthropogenic influences such as harvesting regimes and deterioration of water quality), the targeted cultivation of macro- and microalgae for optimised production of seaweed and algal biomass, and primary and secondary metabolites with industrial potential. |
