Sina G. Senji

PhD Candidate in Civil Engineering

Sina Senji is a PhD candidate in geotechnical and lifeline engineering at the University of Colorado Boulder. He studies the performance of rehabilitated pipelines under multiple hazards, including earthquakes, large ground deformations, and cyclic loading demands on buried lifelines. His goal is to provide clear, evidence-based guidance for long-term renewal and risk management.

Sina’s work combines advanced laboratory testing and numerical modeling. His experience includes geotechnical centrifuge testing, dynamic centrifuge testing in a laminar box, full-scale pipeline testing, and cyclic triaxial and resonant column testing. He has also worked on soil–structure interaction, trenchless rehabilitation technologies, and FEM and analytical numerical analysis. Sina is the lead PhD student contributing to ASTM F3777, a new standard for evaluating rehabilitated pipelines. In this role, he helps convert complex test results into practical, industry-ready performance criteria and evaluation procedures.

He has collaborated with several technology providers. For these partners, he has helped design and conduct product tests and prepare reports for ARPA-E (U.S. Department of Energy) and PHMSA (U.S. Department of Transportation). Sina has published peer-reviewed work on pipeline rehabilitation and soil improvement. He has presented his research at ASCE GeoCongress, ASCE Pipelines, American Water Works Association (AWWA) events, and the North American Society for Trenchless Technology (NASTT) No-Dig Show.
