Assoc. Prof. Dr. Elfed Lewis
Head of Department Electronic and Computer Engineering and Director of the Optical Fibre Sensors Research Group
University of Limerick

Elfed Lewis was born in Holyhead, Wales in 1959. He received a B.Eng. Degree in Electrical and Electronic Engineering from University of Liverpool in 1981. He was awarded a Ph.D. from University of Liverpool in 1987 for work on high-speed photography and spectroscopy of electric circuit breaker arcs during the current zero phase. Following this, he worked as development engineer with BICC Telecom. Cables, Prescot, Merseyside in conjunction with University of Liverpool developing chromatic modulation based optical fibre sensors for a wide range of applications. In 1989, he Joined Liverpool John Moores University where he initiated the research activity in Optical Fibre Sensors. The group investigated sensors for environmental monitoring including water contamination and pH.

In 1996 he joined University of Limerick. He is Head of Department Electronic and Computer Engineering and Director of the Optical Fibre Sensors Research Group, which he founded in 1996. The group are primarily engaged in investigating sensors for environmental monitoring (e.g. water quality, vehicle exhaust emissions, UV light intensity), food quality assessment and parameters associated with high power microwave sources (e.g. Electric Field, Electron Beam proximity).

Elfed is Fellow of Institute of Physics, IET, BCS and Senior member IEEE. He has authored and co authored more than 70 journal papers and made in excess of 200 contributions to international conferences. He currently holds 7 patents on Optical Fibre Sensor Devices. The Optical Fibre Sensors Research Centre under the leadership of Professor Lewis is engaged in investigating sensors for environmental monitoring (e.g. water quality, vehicle exhaust emissions,), food quality assessment and parameters of high power microwave sources (e.g. Electric Field, Electron Beam proximity) and medical devices. In 2005 he was recipient of the University of Limerick Special Achievement in Research Award and was a Fulbright Scholar with CREOL (University of Central Florida) in 2008. He was also Distinguished Lecturer for IEEE Sensors Council for the period July 2013-June 2015.

Dr. Anthony Grehan

Dr. Anthony Grehan
Senior Research Fellow
National University of Ireland, Galway

Dr. Grehan is a Senior Research Fellow in the discipline of Earth and OceanSciences, School of Natural Sciences, at the National University of Ireland, Galway. He obtained his PhD in Zoology in Ireland before undertaking post-doctoral studies at the Université Pierre-et-Marie-Curie, Paris VI (Laboratoire Arago, Banyuls) and at the Université du Québec in Rimouski and Montreal, Canada. This work primarily focused on benthic mapping/monitoring and environmental assessments of estuaries, embayments and coastal seas, and of hydrothermal vent and seep areas, in the deep-sea.

Over the past 10 years Dr. Grehan has focused his research efforts on the mapping/characterisation, habitat suitability modeling, identification of impacts and conservation of cold-water coral reefs and the sustainable management of deep-sea resources in general. He is former chair of the Irish Coral Reef Task Force - a cross sectoral forum - that brought the need to conserve Irish coral reefs to the attention of the media and policy makers in Ireland. This ultimately paved the way for Ireland to be the first country in the European Union to protect cold-water coral reefs under the EU Habitats Directive. Dr. Grehan has developed a keen awareness of policy matters and has co-authored legal and socio-economic papers addressing important aspects of sustainable development.

Dr. Grehan has almost 18 years of experience working in European funded marine projects and currently coordinates the 11 country, large integrating EU FP7 project: 'CoralFISH' - Ecosystem based management of deep-sea corals, fish and fisheries ( Dr. Grehan is a member of the International Council for the Exploration of the Sea (ICES) working groups on Deep-Sea Ecosystems and Marine Habitat Mapping and has chaired an EC Scientific, Technical and Economic Committee for Fisheries (STECF) working group evaluating the effectiveness of marine protected areas as tools in fisheries management. In 2009 he was invited by the French Department of Ecology, Energy, Sustainable Development and Spatial Planning, as an international expert to participate in a Commission examining the long-term sustainability of the French deep-sea fishing industry. He recently completed a review of European funded climate change research in the NE Atlantic as part of the EU FP7 CLAMER project. He has contributed to a number of European research foresight reports.

Dr. Grehan has been an EC expert evaluator during the last three framework programmes: FP5, FP6 and FP7 and recently acted as an FP6 project reviewer and has reviewed scientific papers for numerous scientific journals, books and conference proceedings. Dr. Grehan is an active sea-going scientist, participating in c. 20 full-ocean going expeditions including 10 ROV/submersible expeditions and has been chief scientist on three recent Celtic Explorer expeditions in 2005, 2009 and 2010.

Dr. Allister Furey

He received his BSc honours (2002) in Neuroscience from University College London, specializing in neural computation. He then received an MSc in Evolutionary and Adaptive systems (2004) from the University of Sussex, UK, building computational models of biological systems and focusing on practical applications for his MSc thesis, building a rotation, translation and scale invariant object recognition system inspired by the mammalian visual cortex.

He is currently awaiting examination of his PhD thesis entitled 'Evolutionary Robotics in Airborne Wind Energy applications', at the University of Sussex and is working on a collaborative project between Altius Wind Energy and University of Limerick. 

Research interests include high altitude wind energy, neural networks for adaptive control of underspecified systems, evolution of physical models, dynamic neural networks e.g. spiking networks and CTRNNs, genetic algorithms for optimisation.
