Dr. Khaled Ibrahimi is an assistant professor of Soil Science at the Higher Agronomic Institute of Chott-Mariem, The University of Sousse, Tunisia. He graduated with a degree in Soil Science and Environment in 2001 from the National Agronomic Institute of Tunisia. Then, he earned his Master’s degree in sustainable management of arid zone resources in 2003 from the same academic institution. From the year 2005 until 2007 he worked as a soil scientist in the National Center for Agronomic Studies where he had the opportunity to work in teams that included engineers from various disciplines. In March 2011, he received his Ph.D. in Soil Physics and Soil Hydrology, Department of Biological and Environmental Engineering, Graduate School of Agricultural and Life Science, The University of Tokyo, Japan. He then continued working at the same University as a postdoctoral researcher before he was appointed as an assistant professor at the University of Sousse in January 2013. His research interests broadly encompass soil physics, soil hydrology, environment, resource management in arid and semi-arid areas as well as usage of GIS and remote sensing tools for development and sustainability studies. He has a strong interest as well in combining experiments with quantitative models to explore the complex physical and chemical processes associated with unsaturated flow and transport across variable land use and scales.
