Groundwater and Ecosystems

Luís Ribeiro graduated in Mining Engineering at the Instituto Superior Técnico (IST) of the Technical University of Lisbon (UTL) in Lisbon, Portugal in 1978 and completed his PhD in Mining Engineering (Hydrogeology) at IST-UTL in 1992. He is currently Associate Professor at IST, Director of the Geo-Systems Centre/CVRM, and President of the Portuguese Chapter of the International Association of Hydrogeologists (IAH). He was also President of the Scientific Committee of XXXV IAH Congress “Groundwater and Ecosystems” held in Lisbon in 2007.Tibor Y. Stigter completed his MSc in Geographical Hydrology in 1997 at the Vrije Universiteit Amsterdam, the Netherlands and his PhD in Engineering Sciences (Hydrogeology) in 2005 at the Instituto Superior Técnico (IST), Lisbon, Portugal. He has worked and taught classes at the Universidade do Algarve (UALG) in Faro, Portugal. He currently holds a Researcher position from IST, working on groundwater, contamination, climate change and sustainability. As a member of the Geo-Systems Centre/CVRM, he works both at IST and UALG, coordinating research projects and supervising MSc and PhD students. M. Teresa Condesso de Melo graduated in Geology from the University of Coimbra, Portugal in 1992, completed her MSc in Groundwater Hydrology at the Universitat Politècnica de Catalunya (UPC), Barcelona, Spain in 1996 and her PhD in Geosciences (Hydrogeology) with a sandwich PhD project at the Hydrogeology Group of the British Geological Survey (BGS), Wallingford, UK and the University of Aveiro (UA), Aveiro, Portugal in 2002. In 2006 she became a Guest Professor of hydrogeology at the University of Aveiro, and she now holds a research position at the Instituto Superior Técnico (IST), Lisbon, Portugal.Born in 1961 in Sardoal, Portugal, António Chambel obtained his PhD in Geology, specialising in Hydrogeology, at the University of Évora, Portugal,
