Ayman Abed

Senior Lecturer, Architecture and Civil Engineering, Geology and Geotechnics, Geotechnics

Ayman Abed is a Senior Lecturer in the Division of Geology and Geotechnics, research group Geotechnics. He is interested in studying the coupled thermo-hydro-mechanical-chemical (THMC) behavior of unsaturated soil. One of the main purposes of his research is to provide practical engineering solutions to confront the challenges associated with global climate change. Ayman is an expert in unsaturated soil mechanics, constitutive modeling, and numerical analyses.
