Paul Alexandre studied geology at the Université de Lyon, France, before obtaining a PhD at the Université de Lorraine in Nancy, France, in geochronology and thermochronology applied to tectonic evolution. Between 2000 and 2015, he worked at Queen’s University, Canada, teaching geochemistry and conducting research in geochronology, economic geology, and mineralogy. Since 2016, he is professor at Brandon University, Canada, teaching a variety of courses and conducting research in economic geology and mineralogy. Paul is an accomplished educator and researcher, with numerous peer-reviewed papers, conference presentations, and a textbook to his credit. He is guest editor and associate editor of several publications and a councilor of the Geological Association of Canada.

Joan Garcia (1966) is Full Professor of Environmental Engineering at the Department of Civil and Environmental Engineering of the Universitat Politècnica de Catalunya (UPC). Joan obtained his degree in Biology in 1990 at the Universitat de Barcelona (UB) and in 1991 started to work as Assistant Professor in Environmental Engineering at UPC. Joan presented his PhD on wastewater treatment engineering in 1996 at the UB, while at the same teaching at the Civil Engineering School of the UPC. He has been a postdoc research visitor at University of California at Berkeley (2001), and University of Ghent, Belgium (2005). For his contributions to water resources research and wastewater engineering Joan received in 2008 an award of the Spanish Ministry of Science and Innovation for the Intensification of Research Activity. In 2018, Joan was awarded with a Fulbright Comission mobility grant to develop a research stay in the Everglades Wetland Research Center, Florida Gulf Coast University, Naples, Florida, US. He has written over 250 articles in scientific as well as technical journals and proceedings. H = 46.
Joan carries out interdisciplinary research on the development and improvement of environmental technologies that mimicking nature and maximizing eco-efficiency allow treatment of wastewaters and other kinds of wastes. In particular research is currently conducted on systems for wastewater treatment and at the same time materials and energy recovery, like constructed wetlands and microalgae photobioreactors.

Dr. Lorraine Tighe (Sher/Her) obtained her Ph.D. (Earth Sciences - Physics) from Carleton University in Ottawa, Ontario, Canada, a graduate diploma in Remote Sensing (Geology) from the Nova Scotia Community College, and a B.Sc. (Physics and Geology) from Acadia University in Wolfville, Nova Scotia. She currently works at Environmental Systems Research Institute (Esri) as the Director of Earth Sciences Solutions; Dr. Tighe oversees expanding the use of Esri software and technologies across six Earth sciences disciplines (geoscience, environmental monitoring, sustainable energy, climate science, GIS weather, and marine science). She has lectured on extracting geological information from interferometric SAR (InSAR) and optical data using GIS. Her graduate thesis focused on the extraction of mineralization along a fault zone using remotely sensed data in a GIS. She has published various papers in journals.
