Biographical note

Prof. Dr. Basem Zoheir is a full Professor of Mineralogy and Economic Geology at Benha University (Egypt), and now AvH fellow at Kiel Univ. (Germany). He was a DAAD doctorate at the Univ. of Munich (Germany), visiting researcher at the universities of Tubingen, TU Clausthal, Geneva, Stockholm, Graz, TU Lulea, and a fulbrighter at the USGS DFC-Denver. Basem has published around 42 articles in international peer-reviewed ISI journals. He served as a reviewer and guest editor for a number of Geoscience journals, and as an examiner for several research funding institutions. Aside the academic work, Basem provided consultations to national and international mining companies exploring for gold in the Nubian Shield.

Dr. Domenico M. Doronzo holds a B.Sc., a M.Sc., and a Ph.D. degree (in 2011) in Earth Sciences from Università degli Studi di Bari Aldo Moro, Italy. Theses and specialties related to the degrees are physical volcanology, experimental and computational fluid dynamics, petrology, and natural hazards. Then he has worked in volcanology and sedimentology, fluid dynamics and combustion, environmental sciences, and rock physics in the United States, Italy, and Mexico. He is currently a contract Researcher at Consejo Superior de Investigaciones Cientificas, Spain. Particularly, he has received the Rittmann Medal (in 2014) from Associazione Italiana di Vulcanologia, which is assigned to the best young Italian volcanologist. His research interests focus on integrating theory, field, numerical modeling, experiments and laboratory to study geological processes and products in volcanic areas from fluid dynamic and natural hazard perspectives. Particularly, he studies pyroclastic energy currents, sand and dust storms, turbidity currents, man-made environmental phenomena, and georesources. He has recently coordinated the Topical Collection on Dust for the Arabian Journal of Geosciences. He is an Associate Editor of the Arabian Journal of Geosciencesresponsible for evaluating submissions in the fields of Petrology, Volcanology, and Georesources, and also is an Assistant Editor supporting the Editor-in-Chief.

Prof. Dr. Emanuela Schingaro holds a B.  in Physics (1990), a Ph.D.  in Earth Sciences (1994) from Università degli Studi di Bari (Italy).Presently she is  associate professor of Mineralogy at  Department of Earth and Environmental Sciences of  Università degli Studi di Bari ALDO MORO (Italy). The scientific activity is mainly focused in the field of the mineralogical crystallography (single crystal and powder X-ray diffraction).  Research interests: crystal chemical characterization of complex silicate minerals; relationships between crystal chemistry and geologic environments/petrogenetic conditions;  clay minerals characterization; structure and disorder in rare mineral phases; thermal behavior of minerals and  their solid state transformations. Collaboration with scientific societies: 2002-2004 Counselor of Italian Society of Mineralogy and Petrology (SIMP); 2007--2012 Counselor of the Gruppo Nazionale di Mineralogia (GNM); 2015-2017 Component of the Teaching Committee of  the Associazione Italiana di Cristallografia (AIC) – Italian Association of Crystallography. From 1/12/2015 to 1/11/2018 Elected as Representative of the Scientific Area 04 (Earth Sciences ) in the Academic Senate. From 31/10/2014 to present : member of the Task Force of University of Bari  Research. In 2018 she joined the AJGS as an Associate Editor responsible for evaluating submissions in the field  of Mineralogy.

Dr. John S. Armstrong-Altrin holds a MSc in Geology (1993) from Madurai Kamaraj University (V.O.Chidambaram College, Tuticorin, Tamil Nadu, India) and a Ph.D in Geology with a specialization in Sedimentology (1999) from University of Madras (India). He has completed his postdoctoral research (2003) at the Renewable Energy Institute (IER), Temixco, Mexico. He is currently a senior researcher at the Institute of Marine Sciences and Limnology of the National Autonomous University of Mexico, Mexico City. His research interests focus on sediment provenance, geochemistry, tectonic environments, and U-Pb geochronology of zircon grains. He has conducted a good number of research projects on coastal and deep-sea sediments of the Gulf of Mexico. He has published more than 60 research articles in indexed refereed Journals. He is one of the Associate Editors in the AJGS and responsible for evaluating submissions in the fields of geochemistry, sediment provenance, sedimentology and tectonics.
