Ehsan Abdi is a faculty member at the University of Tehran, Iran, with research interests in forest engineering, forest ecology, soil bioengineering, and root biomechanics. His research focuses particularly on the mechanical role of plant roots in soil reinforcement, slope stabilization, erosion control, and nature-based solutions. His research also encompasses forest road engineering, including forest road planning, maintenance prioritization, spatial multi-criteria decision analysis (MCDA), GIS-based decision support systems, and sustainable management of forest road networks. He has applied methods such as the Analytical Hierarchy Process (AHP), Delphi technique, weighted linear combination, and spatial analysis to support infrastructure management and environmental decision-making. His broader research interests include forest ecosystem management, soil and water conservation, bioengineering approaches to slope stabilization, and the application of nature-based solutions in forest environments, particularly in the Hyrcanian forests of northern Iran. He is interested in international research collaboration and interdisciplinary studies integrating forest engineering, geospatial analysis, road ecology, and soil bioengineering.
