Research

Geotechnical Engineering is a branch of Civil Engineering that deals with the design, analysis, and construction of foundations, slopes, retaining structures, and other systems that are made of or supported by soil or rock. As a geotechnical engineer, my research interests include:

• LRFD design of deep foundations
• Driven pile setup (freeze) prediction methods
• Soil\structure interaction
• Trenchless pipeline infrastructure installation and rehabilitation techniques
