Landslide Prediction and Susceptibility Mapping Using Interferometric Synthetic Aperture Radar (InSAR):A Case Study of Maryland
About the Topic:
This presentation introduces ongoing research at Morgan State University on an end-to-end, data-driven approach to improving transportation corridor safety by combining satellite remote sensing with sustainable slope-stabilization strategies. Using Synthetic Aperture Radar (SAR) satellite imagery and Interferometric SAR (InSAR) time-series analysis, this approach detects millimeter-scale ground deformation along highway and railway slopes and supports early identification of landslide-prone areas. The talk highlights how multi-source data integration and machine learning can be used to map landslide susceptibility, track deformation trends over time, and prioritize high-risk zones for intervention. Finally, the presentation connects early-warning outputs to practical mitigation solutions, including the use of sustainable fiber-reinforced materials to strengthen vulnerable slopes and improve the long-term resilience of transportation infrastructure.

About the Speaker:
Tohid Asheghimehmandari, Ph.D.
Postdoctoral Scholar, Morgan State University (Baltimore, MD)
Dr. Mehmandari is a geotechnical and geohazard researcher specializing in transportation infrastructure safety, slope stability, and landslide risk mitigation. His work focuses on integrating satellite-based deformation monitoring (SBAS-InSAR / PS-InSAR), geotechnical numerical simulation, image processing, and hybrid machine learning to support real-time hazard mapping and early-warning systems for U.S. highways and rail corridors. With more than 10 years of experience in geotechnical engineering, and as a senior contributor to geotechnical and structural laboratory research activities, he has published more than 14 peer-reviewed technical journal papers and book chapters, including works with Elsevier and Springer. He is currently a Postdoctoral Scholar at Morgan State University and contributes to U.S. Department of Transportation projects, led by Professor Zhuping Sheng, sponsored by the National University Transportation Center-Safety21 Program, in collaboration with Carnegie Mellon University (lead institute), research teams, and transportation agencies and support by the Department of Education. His research also advances sustainable mitigation strategies using recycled and eco-friendly fiber-reinforced materials to enhance the durability, safety, and cost-effectiveness of slope stabilization solutions.
