Dr. Haytham Mohamed Salem holds a Ph.D. from the Polytechnic University of Madrid (Spain), specializing in the effects of conservation tillage systems on soil properties and erosion control in arid and semi-arid regions. Currently serving as a postdoctoral fellow in the Department of Soil and Water Systems at the University of Idaho, USA, Dr. Salem boasts over 15 years of experience as a Soil and Water Conservation researcher at the Desert Research Center (DRC, Egypt). Additionally, he has held a research position at the Key Laboratory of Digital Land and Resources, East China University of Technology (ECUT, China) from 2019 to 2021. Dr. Salem has made significant contributions to exploring the spatial variability and characteristics of soil fertility parameters, identifying key indicators for soil quality index, and delineating potential management zones. His expertise extends to regenerative agriculture practices, greenhouse gas emission studies, auto-controlled rainfall simulators for monitoring runoff and soil loss, and innovative designs like the Combination Machine for In-situ Rainwater Harvesting and Soil Erosion Control.
