Siva Sivathayalan

Professor Siva Sivathayalan, affiliated with Carleton University's Civil and Environmental Engineering department, is a leading expert in geotechnical engineering. His teaching includes advanced courses like Foundation Engineering and Advanced Soil Mechanics, alongside previous roles in instructing Mechanics and Geotechnical Project courses.

• B.Sc. Engineering from University of Peradeniya
• M.A.Sc. and Ph.D. from University of British Columbia

Research focuses on static and dynamic soil behavior, liquefaction, laboratory testing, constitutive relations, and geosynthetics. Studies emphasize principal stress rotation, seismic loading, and generalized strain paths, as evidenced by his 2024–2022 publications.

Recent work explores liquefaction under complex seismic conditions, refined specimen techniques for tailings, and soil-structure interactions in buried culverts. His lab's hollow cylinder torsional shear device enables precision in stress path analysis.

• Scientific Awards: Stermac Award (2010), ASTM Award (2001)

Advisees include 22 graduate researchers, with co-supervision roles in projects addressing stochastic systems, soil anisotropy, and corrosion impacts on infrastructure. Publications span 1994–2024, focusing on sand liquefaction, stress history effects, and geotechnical failure mechanisms.
