Ali has led multidisciplinary projects for his clients including geotechnical investigation, foundation design and construction QA/QC for major wind farms, infrastructures and landfills. The projects included the assessment of dynamic properties of subsurface soil layers, geophysical investigations, detail settlement and bearing capacity evaluations, and the design of massive raft foundations for wind turbines.
He played key roles assisting clients with the investigation, data analysis, geohazard assessment, report preparation, and risk evaluation for major tunneling projects including sewage system and forcemains. Additionally, Ali completed dam safety reviews, dam and water retaining structures design, and mining dam designs and assessments. His major recent roles include helping clients complete safety assessments, geotechnical evaluations and stability/seepage analysis, seismic settlement assessment and failure mode analysis, audit inspections, and mine closure cost estimates for dams and water/tailing retaining structures.
To advance the state of practice, Ali has promoted the use of the Multichannel Analysis of Surface Waves (MASW) method to assess soil dynamic properties, characterize subsurface soil and rock properties, and locate underground cavities and fault/joint locations within rock formations. Based on field experiments, he developed a method to enhance the quality of geophysical field data entitled Multi Geometry Approach for MASW Survey (Nasseri-Moghaddam and Park, 2010).
Ali currently serves as the Chair of the Canadian Geotechnical Society (Southern Ontario Section), is an active member of the Canadian Dam Association, and is a member of the Canadian Association of Earthquake Engineering. He has also been a lecturer at the University of Waterloo where he taught undergraduate and graduate level courses including Advanced Soil Testing in Geotechnical Engineering. As an invited speaker, he regularly shares the results of his works and experiences at universities and workshops. He also, publishes the results of his works in conference and refereed journal papers.
